  1. good day i am delayed for 3 days now i am experiencing nausea and lower back pain.. Me and my bf tried it but not totally do it. is there a tendency that I am pregnant?

    1. With 3 days late it is time to take a test ! Be careful also when we try to conceive we are too listening to our body and it can mislead you in pregnancy symptoms. Best of the luck in your project !

  2. My husband and i are trying to conceive and i believe that i am pregnant but it has only been 1.5 weeks since my supposed ovulation but my body feels different. I am more hungry, it kind of hurts to lay on my stomach, and i am feeling weird tickling in my uterus and it has felt like this since yesterday May 18 2014. Is there any way that i could be feeling my pregnancy before it even registers on a hpt, or could it just be in my head because of trying to gt pregnant?

    1. Hi,
      most of the women doesn’t feel the pregnancy symptoms before having their morning sickness which will generally occur pass 8 weeks … Being listening too much to your body to be hinted of a pregnancy can also make you feeling a lot of different symptoms that you really want to have ! 14 days past your ovulation date will be the good moment ti do a pregnancy test if your cycle is irregular or 3 to 7 days past your next period expected date if you are regular. Good luck !

  3. Hi, my last period started 13th April and it ended 18th April (6 days and 30 days cycle). I had unprotected intercourse with my bf on 19th April and 22nd April. And protected intercourse on 11th May as I calculated my period supposed to come on 13th May and it may be safe to have protective sex on days which are nearer period coming days.
    Now 20th May , period still haven’t come and I haven’t checked the test.
    My questions are that ;
    1) Is that possible to get pregnant even though using condom ?
    2) 19th April & 22nd April dates which I just had finished my period and are these days not safe? How can I calculate which days are safe to have unprotected sex during one period from another.
    3) I had spot bleeding for 2 days, on 9th and 10th May. is that the sign of eggs implantation ?

    Thanks.
    With Regards,
    Julie

    1. Hi, you have pretty good questions !
      First the use of the condom is a good way to prevent pregnancy but is not 100 % sure it depend of the way it is used and if you make sure once removed that there was no defect and no leak from it. Second there is no safe day on a cycle to have unprotected sex for someone that does not want to get pregnant. You can have multiple ovulation in a month, which i personally experienced a few years ago and got pregnant on the last days of my periods. Trying to conceive at the time no protection was used what so ever. But some women have 2 weeks cycle of ovulation , one release on each side a month or other have an ovulation on demand … which a desire of pregnancy can trigger a random ovulation. Spotting is sign of implantation but not a guarantee of it. It was close to your next period cycle and can be only the beginning of it. Good luck !

  4. last march I had my period on the 14th then april 8th and now may 13 why is it like that?

    1. Hi , you most likely have an irregular menstrual cycle. It is a common thing, for different reason as sport or stress or just randomly. To make it being regular you can take a birth control pill to help. Or always count your first day of your period as day 1 of your cycle and the day 10 to 16 your most fertile period. This way you will be able to track your system even if you are not regular. Good luck

    2. Sometime your 2 ovaries might work on a different schedule so you will have a very short cycle. To help, taking birth control pill , could synchronize them and will relieve you to have period every 3 weeks , Normal cycle is indeed between 21 to 32 days.. Most of the women have a 28 days routine. A visit to your doctor office might give you good answers.

      good luck

  5. Trying to calculate my ovulation window… My menstration starts with a light spotting, for about 2-4 days prior the heavy bleeding. How do I calculate my menstral cycle??? Do I count from the light spotting, or do I count from the heavy bleeding…? When does my cycle officially starts? Thanking you in advance…

  6. OK.. So lost..I had a period on 2/13/14 was regular next 3/13/14 came early then on 3/30/14 light for 5 days. Then 4/30/14 came 3 days late .. And was also light.. May still waiting haven’t came.. When should I have my next cycle. Not stressed or anything..

  7. I had my period last April 25,2014 till April 29.
    When will be my next cycle for the month of May 2014?

  8. The length of my menstrul cycle is 25 days, and my period last 1-3 days .is this normal.?

    1. Yes it is all normal, every women have different cycle between 21 to 32 days and period holding 1 to 8 days. Some women will have light period like bleeding on the first months of the pregnancy too. If you always been like this I would not worry but if it is a new state for a few months, I recommend you to make a test.

      good luck

  9. I had unprotected sex on 20th day from the day my periods started (26/4/14). Regular menstrual cycle is 28 days. My due is on 24th May 14 & today its 26th May 14, still periods not started. Will Mensovit plus help me to avoid pregnancy? If not what should i take to avoid pregnancy. I don’t want to go for a medical test.

    1. emergency birth control pill are effective when taken within 72h of the unprotected sex… by now it is already too late. A pregnancy test , pee on a stick will indicate you when you will be late for your period if you got pregnant or not, you might have to see a doctor from there depending of the result.

      good luck

  10. my period was late 4 days and when it came it lasted about 3 to 4 days what could it be? my periods come every 28 days and last 6 days. but this time it was late and only lasted a few days, any advice what could it be the cause to that? I have been feeling a lot of cramps lower back aches tones of headaches tender boobs nausea body temp up and down a lot more tired then usual some time dizzy and more what could it be. any advice?

    1. Having your period is not a 100 % sure confirmation that you are not pregnant. But before looking in this direction Often periods will trigger symptoms as you described, stress and changes in your life as starting doing regular sport or a new job can delay your cycle. Take a test to clear out your mind or a possible pregnancy, if you were not trying to conceive.

      good luck

    My period came on the 4th of january 2014 and 3rd of feb,29th of march,24th of april and also 20th of may.please, i want to know if it is normal that way and also,what day could be my most fertile day to concive because i and my hubby have been on this for close to two years now. I need your assistance on what to do… Thanks.

    1. you have an irregular cycle, in these cases there is one good way to set yourself. The first day of your period is the day 1 or your cycle. for irregular cycle to be on the safe side your fertile window will be between the day 12 and 18. While being in this window, have intimacy one day on two not more. It will allow more mature spermatozoides to be involved in the conception of your child.

      good luck

  12. my period was Jan 14 feb 13 march 14 and april 8 then may 13.
    I stopped birth controll pill from april 8 so that is one month and then i started taking again last may 13. I notice some changes in my areola and nipple its darker its sore and tender before period and goes off after the period. but still its dark and have a tingling sensation specially when it is called had unprotected sex since I went of the pill for a month. took pregnancy test on april 7 11 and 17 came out negative. i’m not nauseated and don’t feel dizzy. still confused if last may 13 is a period or not it lasted for three days 1st and 2nd day was heavy third and fourth day not that much the color is bright red and have clutch i think like a cranberry juice. am i pregnant?

    1. Stopping and starting your birth control pill had for sure an incidence on your body as the hormonal level that was more stable ran a bit up and down lately. Did you stopped your pill cause you wanted to become pregnant or you had issues with it ? count 21 days since the day 1 of your last period. If you passed that day take a test again if it turns negative and you still have doubt a visit to your doctor might help you to have a resolution as a blood screening will clear out any doubt.
      Good luck !

  13. i had issues with the pill it just like a very painful headache. I have been on a lot of stress lack of sleep, changes in my job. and bereavement.the blood last may 13 was bright bred and have clots 1st day i used 4 pads same as the second day. third and fourth day just two pads.
    I don’t feel dizzy. my breast is not sore now but the areola is dark is it because of the adjustment of my body because I stopped using the pill?

  14. I started my cycle on May 12th & it lasted 3 days which is very normal. I’ve always had a cycle for 3-4 days each month. The beginning of the week May 25th I started to notice my breast was very tender. On the 27th I noticed a white discharge. On the 28th & 29th I had cervical mucus, I was very wet. I know it was most likely my ovulation week. On May 29th the same day the cervical mucus was present I had unprotected sex but he pulled out. The ovulation calculator said my most likely fertile were May 23rd-May 28th. Do you think I may conceive due to ovulating & using the pull out method? When should I take an test?

    1. The pulling out method is a only 75 % accurate contraceptive method .. for those who can do it well. Knowing that you were fully in your ovulation drop the chance of contraception for this method at 50 % . Wait for your period to be due, if they don’t start, which might happen only due to the stress of the possible conception, let an extra 3 days pass, and do a pee on a stick test with the morning urine. That urine will contain a higher concentration of HCG that any other during the day, if you had conceive you ill then know.

      Good luck

  15. Ayo is my name
    My period came on the 3rd of febuary and 29 of march,24 of april and 20th of may, but the one im the month of may only lasted for two days of which it has not happen before, so please, i want to know if it is normal that way and if not, what am l suppose to do in this case? I and my hubby have been trying to have our baby for close totwo years now so please any thing to help will be appreciate,Thanks so much, will be waiting your reply…

    1. Hi , conceiving is not an easy task ! Conception stress is not helping you either ! then, what I would recommend you to help you to conceive, to make sure you don’t miss your fertile window is pretty simple, I got pregnant on the first try 3 time already following this guide that was given to me many years ago. Your period being day 1 of your cycle start to have intercourse ONE DAY ON TWO ONLY to allow more mature spermatozoides to hang around, they survive in the womb 72 hours so you will be well covered all the time, the time to wait your ovulation to be completed. Start day 10 o day 17 of your cycle. Which will enlarge your chances to conceive a lot as you enlarge your window and the maturity of the spermatozoides. Having a 2 days periods can happen if you had started to do more sport, changed job or have more difficulty to sleep due to numerous factors.

      good luck !

  16. Hi,
    I have been trying to conceive for the past 5 months and we have been unsuccessful….I am trying to follow the ovulation dates as well the fertility window suggested by the various websites but am really dejected now. My cycle is pretty regular…..2-3 days off but it used to be pretty accurate by the exact date. I am 34 years old and really want to have my 2nd baby soon……we had no issues with our first one. My periods started on MAy 31 this time and MAy 3rd before that and then April 4th the previous month. Please advise as I am on the verge on depression……also we try and have sex about 3 times during this fertility window and somehow I feel we may be missing the dates…..I am not sure why else might be wrong! Need your advice and help desperately! Thanks.

    1. Hi ,
      first of all conception stress is your worst enemy… then, what I would recommend you to help you to conceive, to make sure you don’t miss your fertile window is pretty simple, I got pregnant on the first try 3 time already following this guide that was given to me many years ago.

  17. Hi, my period start on 11th April, 7th of may, 1st june. It occurs every 21 days. Please is it normal and when are my safe days to have unprotected sex

    1. having a short cycle is not preventing you to ovulate ! You have an early window more day 10 to 13 then 13 to 17, but conceiving is possible

      have a nice day

  18. if the man should put on condom and the girl is on trousers the man used his dick to rub the vaginal while she is on her trousers the he ejaculated in the condom will she get pregnant?

  19. i had sex with condom 9days to my period and the condom break then i took pill within 24hours will i become pregnant

    1. if they haven’t broke – no. but this a very bad practice. using two condoms at once increase the chance of breakage. use one condom
