  1. Hello I need a little help. My last cycle started on 5/26/15 and ended on 6/1/2014which was 7 days my cycle is normally only 4 days but I was taking north control and the month in may I took ovulation pills for 5 days so I’m not sure if that is why I didn’t ovulate I’m not sure so I had unprotected sex on 6/7/2014 only one time and when I calculated using the ovulation calculator it said that my most fertile days would be between 6/6/2014 to 6/10/2014 so since I had unprotected sex on 6/7/2014 when would I know if I’m pregnant or not please help us because we are really trying to conceive.

    1. you will know it will be the time to take pregnancy test when you will be late for your next cycle, are you regular ? if yes it will be easy if not it takes 21 days from the first day of your fertility windows to be considered late for irregular cycle.

      good luck !

  2. Hi..

    Thanks!

  3. I last saw my period 11th may I took postinor 2 and I started bleeding 20-22nd may. at 29 or 30th may I had sex used condom it broke and I took postinor with in 24 hours and the second drug 15hours later because it was stated in the postinor 2 drug slip dat at most 16hours gap .my period is 29days cycle hence from 11th may, the next period is suppose to be 8th June till now I haven’t seen it I took blood pregnancy Test twice on 9th June both were negative pls what could be the cause of the delay in period

    1. pls I need your reply I just did another test and it negative and I am beginning to have dark brown discharge

      1. When you take emergency birth control medication your entire cycle is messed up you can need 2 cycles to get back regular. As you triggered period there is no endometrial to expelled at the period that should normally follow. Brown discharge is slow bleeding if you had since you had your last broken condom incident, a blood test, which is much more precise than a pee on a stick one, and it came back negative. I think that you can sleep on your 2 ears. Please be more careful and do not use emergency birth control pill as a regular back up plan.

        good luck

    1. Lisa, there’s always a risk involved, even when you use a condom. considering the situation, I suggest you take a home pregnancy test so you would have a peace of mind. good luck

  6. Hello,

    I last had my menstrual on May 05,2014. I did spot on Sunday June 1-June 6 but very light. Enough to only need a panty liner all day. I am a heavy bleeder. Could it means I am pregnant? Also, my breast do become tender and they weer not tender the week of my spotting days. I did feel a little tenderness today but still no sign of menstrual. I also started working out and taking diet pills. I know that can also take affect on my menstrual. Please advise.

    1. Dieting and physical fitness is known cause of change in the menstrual cycle. Most of the athlete does not even have periods. Military female personnel either …If you are worried a test will clear your mind, your cycle will adjust to your new life style !

      good luck

  7. Hi, my last menstruation was may 13 and I had sex last may 23. till now my period still did not come. I felt the following: dizzy, sore breast, nauseous, headache, cramping goes on and off. I don’t want to take the pregnancy test as I am afraid that the result might be positive.

    1. Well my dear, it will be time to take a test, as better knowing what is going and taking the right decision… your last intimacy date was into your fertile window. Either the period are not starting due to the stress, or it is because you are on the way. If conceiving is not in your plan, the earliest you know you are pregnant, easier it will be to meet a specialist in a family planning clinic and decide what will be your options.

      good luck

  8. My period for the past few years has been irregular. I would not have it for 2 to 3 months and then when it came i would be on it for 2 to 3 weeks at a time. as of last august 2013 my cycle has been on schedule give or take 1or 2 days. I have not seen my cycle since april 16th my boyfriend and I had sex on the regular but he would pull out before. I took 3 pregnancy test 2 weeks ago but they came out negative. I dont want to go to doctor because i don’t want the disappointment again but i know i need to go. im just a bit confused because im wondering if it is my cycle just playing tricks on me again.

    1. A lot of women have irregular cycle all their life … If you are not trying to conceive birth control pill will help you to have a regular 28-30 days cycle. If you are trying to conceive , well have intercourse every 48h not more as soon your periods are over until the next.

      good luck

  9. I had unprotected sex Jun 2 and 3. My last period started May 20th. Is it too early to take a test. The one I took today was negative put it also was expired.

  10. I just used the period calculator because i noticed i am four days late fo my period and it just confirmed truly that i am late.i am now scared to take a home pregnancy test because im so desperate to get pregnant so i fear getting disappointed.should i wait for a week before doing the tests or what are my chances of this being my lucky month?

    1. Hi ,

      take the test you need to know, just the stress you cause to your body being desperate to conceive can delay your period. Better to clear that up a negative test ght trigger the period, a positive one will make you celebrate dont keep the suspense unnecessarity.

      Good luck !

  11. Thank you so much clepetark for the good job you are doing pls I want to know if a man should put on condom and he used his dick to rub the vaginal (no insertion)of his woman the condom got broken when there is no precum(that is the condom was dried) will the woman need to take ECP drug?

    1. Hi If I understood correct, your partner is teasing you on your pubic area, without penetration with no protection and you wonder if there is no precum if you should take ECP ?

      The odds are that most likely you will not need to worry about this action as there is a very little, but verrryyyy little chance to have spermatozoid in the precum, if no penetration is added to the equation I think you can sleep tight. But ! you are playing with fire as, when we are very aroused by these game often we don’t only tease but can lose control and go for full intercourse with no protection. Either you protect yourself properly or you keep the discipline tight

      Good luck

  12. My period was June 15, after 5 days we had sex, now I am getting back pain stomach pain and also am very tired. Are these the symptoms of pregnancy

    1. Hi ,

      This is a way to early in your cycle, but some women are experiencing multiple ovulation during their cycle. if you are worried better for you to do a pee on the stick test on day 21 of your cycle, starting to count on day one of your last period. Sometime the guilt feeling of unprotected sex, is making you listening to much to your body and can trigger pregnancy like symptoms. The best way to clear your mind out and avoid delays on your next cycle out of stress is to test yourself.
      Good luck

  13. Hi I had my last period on April 15, 2014. In the month of may didn’t get anything. In the month of June made a doctors appointment so I went on the 6 of june. Did blood and urine both negative. In the 6 I was spotting the doctor check me out all I needed was a panty liner. It was so light son it lasted from the 6 to the 13. Now my calendar is tell me that today the 28 of june I’m suppose to be getting my period. But no sign of it. I am always regular with my period my whole life. Even with stress believe me I get it earlier but it always shows every month. Now I am just waiting to see what’s going to happen. I am 41 very healthy doc said no menopause pad came back normal. So nothing else is wrong with me. When I was pregnant with my two oldest I didn’t know till I was three months. So can anyone share some advice. Thank you ladies

    1. Hi ,

      hum, did you start a new fitness routine or being under a very big stress, change of career the grown up leaving home or graduating university. Menopause can be on and off before being completely engaged, you cam have random cycle before being full stop, but 41 is still young to be menopaused…. some lady turn at 25 but it is very rare. If you skip this cycle. Get a pee on the stick test at the drugstore… being o late if if it a pregnancy it will show, if not it will reinsure you. But the blood screening doesn’t lie … it is jute to make sure you did not get pregnant since … the blood screening.

      good luck

  14. I have a very irregular cycle, I saw my period on the 28th of January, didn’t see it again until March 22nd, then may 18th and now July 3rd. Am not having sex either. Please, what could possibly be responsible and what can I do to get it back to normal. Thanks!

    1. Hi,
      having an irregular cycle is more common that you think but you seems to skipp always a month, there is multiple possible explanation, from just having a long cycle to having only one ovary that function. A medical visit could give you more answers. Extreme sport, stress and very busy lifestyle can also result in skipping cycles, but i don’t think it is why you skip months as it seems to be on your case a long term issue. Birth control pill can force your cycle to settle. Again a medical visit might help you to understand better your cycles. This is nothing urgent, no need to rush to the emergency room for that, but maybe during your next annual visit this should be addressed !

      good luck

  15. Hi, my last period was on the 26th of may,ended on the 2nd of June.. im pretty sure i had the cervical mucus changes somewhere around the 11th of June not really sure for how long as i wasn’t particularly paying close attention,just noticed the changes after being to the toilet. My man an i had sex on the 18th of june..i didnt get my period on the 30th of june as expected so i took a test which was negative, i’m wondering did i test too early?? is there a chance i may be pregnant?? im still yet to see any signs of my period so am a little curious. thanks

    1. Hi,
      Is your cycle regular ? the 18 th was late in your fertility window but still possible… Just the stress of the possibility to be pregnant might delay them. If a pee on a stick result is negative and you still feel unsure a blood screening cannot lie !

      good luck

  16. Hi, im looking to shed some light on an issue i have going on right now and hopefully some one has gone thru something similar and can give me some advice. ok so here’s my situation: my periods are normaly regular so my last period was on june 5 til about the 9th or 10th. i had sex on the 17th and 19th. my period should have been due july 3rd but it is now july 12 and no af. i know its not stress because im very calm seeming how i was not trying to conceive in the first place. anyway ive been having light cramps and feeling a bit more tired lately. i no pregnancy is not the only reason for a late period but im wondering if i could be in fact pregnant. although this was not planned i dont want to get my hopes up to get dissapointed by a negative test. Should i take a test or give it a few more days?

  17. I randomly have irregular periods, my last period was june 13 2014, when do i expect to see my next period?

    1. Hi , as you are saying yourself … you have an irregular cycle …so they are unpredictable…. In order to regularise your cycle in order to have more predictable periods, taking birth control pill can help a lot !

      good luck

  18. Pls I had sex on 20th April 2014.My last period started 14th May.How long is my pregnancy from the day of sex(20th April)to 2nd July?

    1. you date of pregnancy will be the first day of the last period you had before you got pregnant. But if you had periods on may, you will not be pregnant from the april intercourse you had. Once you have a positive pregnancy test in your hand, if you are right now it will be your early july first period day that will be the day 1 of the pregnancy in the calendar.

      good luck

    1. By now a pee on the stick test will give you a clear answer ! as you seems to be very late. It is possible that you just skip a cycle with no reason, or in response to a change in your life as you mentioned stress or starting a work out routine or quitting smoking … Don’t wait, do the test, so you can plan ahead what it is coming or to stop worrying if it is negative. you had intimacy very early in your cycle but it is not impossible depending of the length of your cycle.

      Good luck !

  20. Hello, please i need you to put me through on this issue that have been giving me concern.my march period came on the 29th,April on the 24th,may on the 20th,june on the 14th and then july came 11th, and what i observe now is that,when the period will come, it will only last for 3 days i.e its dried up on the third day and am not comfortable about it. Please i want to know if my period is regular or not and what to do to correct it if its not regular. Also to know my chances of getting pregnant because i really want to get pregnant. Thanks..

    1. Hi , you seem to have a decent cycle. to get pregnant with a short or irregular cycle, the magic recipe is that you have to consider the first day of your period as the day 1 of your cycle. Your fertility window is day 11 to 17. For short cycle we can even push it to be day 9 to 17. During this window, and this is the most important thing … have intimacy only one day on two … to allow more mature spermatozoids to be released. As they live 72h in the womb. there will be always some in between the intercourses and the entire window will be covered as, you might know the egg can be fertilize only a few hour before degrading.

      Good luck
