1. My wife is taking Dromis 30 to avoid getting pregnant. Her doctor suggested to take it from 5th day. But she is confused with the calculations. If her period starts on 2nd Feb at 10pm in the night then is it assumed that the first day continues till 10pm on 3rd Feb. Then is it ok if she has taken the medicine on 7th at 12:30pm?

   1. I’m really sorry, but we cannot give medical advice, especially if she’s taking pills. Please consult her physician

2. I have not had my cycle since January 27,2014 do you think that I may have became pregnant I took a test but it is negative.

   1. Well, there’s a possibility, but periods are often late. Wait a few more days and test again. If you don’t receive your period in the next 14 days, try consulting your physician for a blood test

3. So why do i have mine started today March 3 rd when it is due tomorrow

   1. Our menstrual cycles are not always predictable or regular. It may be that your cycle is just a little shorter this month.

4. My last period started on the 3rd of February and I am still waiting I did two hpt but came out negative. I am waiting few more days untilI do aanother one but do you think I may be pregnant? I did have light spottings a week ago but it was only twice.

   1. It is possible. It is possible the light spotting you mentioned was implantation bleeding, something that commonly happens when the egg is implanting in the uterine lining after fertilization has occurred. However, it is also possible your cycle is late or you may miss a cycle for an unknown reason. If your period hasn’t happened yet, and you are still getting negative pregnancy tests, it is best to consult your gynecologist or family doctor.

5. My last menstrual cycle is on the 22nd Jan 2014. Till now my period had not come. Did a few test but turn out to be negative… is there any possibility I’m pregnant?

   1. It is possible that you are pregnant. It is also possible that you are not. You may simply have missed a cycle due to hormonal fluctuations, sickness, stress, etc. If you are not getting a positive test but are worried about a pregnancy, check with your doctor and ask for a blood test.

6. well i had being having sex even on my ovalution day,,but still unable to concieve,,,i don knw what is the problem..any advice to boost my chances of getting pregnant

   1. Hi, we’ve just wrote an article on how to improve your chances of getting pregnant – check it out here

7. Um taking flex seed oil supplement trying to get pregnat will it help?worried

   1. Flax seed oil can definitely boost your health and nutritional quality, which goes hand in hand with boosting fertility, but it alone will not ensure you will achieve pregnancy.

8. The last time I started my period was feb 20 2014 it is now march 25 and I still haven’t started my period I am 20 years old I weigh bout 120 pounds idk how late I am on my period due to these period caculators on the internet its sayin I shouldve started my period march 20 idk how accurate these are but I’m 5 days late soo am I pregnant I haven’t had no symptoms yet ?

   1. I have the same problem and today its the 27 and still nothing did u get ur period or no ?

      1. It seems like you ladies have the same problem. Most internet period calculators base their calculations on a woman with a 28 day cycle. However, a cycle can vary from about 22-35 days per month. An accurate period date should be based on your average cycle length, and unless you have been tracking it, then you are not able to know whether your period is late or not. The best way to determine this is to take a pregnancy test. Take one a week for two weeks, and if you still haven’t gotten your period, consult your physician.

9. hi,I have a concern ,I feel my breast hurts since a week ago.a lot of fluit from my vagina is coming , lower back pain.headache sometimes.i did since Saturday 22 ,2014 pregnant test and came with a clear line positive,and yesterday Thursday march 26,2014 and also the test came positive a clear line appear .so my question is iam pregnant yes oh no.

   1. If you have gotten two positive pregnancy tests, you are probably pregnant. False negatives can happen, but a false positive is a very rare event indeed. Congratulations!

10. Last period was march1 2014 lasted 5 days.current pediod started march28 2014, planning wedding december20 2014 will i be safe.

11. how can I prevent or delay period (vacation -cruise time)?

    1. find out more about delaying your period in this article

12. hi,my reply is for those who lost their period and thinking that they are pregnant. this issue of pregnant things I think only God knows why it is happening like that, even me myself surviving the same history, during my fertility time I had sex with my hubby but nothing happen,so even if your period is late doesn’t mean that you are pregnant…..

    1. True, but everybody have dreams and hope, fears and bad experience. I think that everybody that comes want to share a part of themselves with people having the same concerns

       have a nice day !

13. My period was on March 10 2014 i stayed on for 6 days now its April 12 when do i post to come on im so scared i hope im pregnant

    1. Hi , if you had your last period on March 10 that mean that you skipped the one due on April 5 th , by now with a week of lateness in your period a pregnancy test should offer you a clear result. Best of the luck !

14. My last period date was 16th march. I m feeding my 10 months baby regularly now a days coz she got fever and dr. Said me to give her mother milk. Can i b pregnant?

    1. Breastfeeding is not a contraceptive method, by now doing a pregnancy test will be a good idea, do it with the morning urine the HCG concentration is higher, you should be fixed. On the other hand breastfeeding is requesting a lot of energy from your body skipping a menstrual cycle is not abnormal. Good luck

15. my last period was on march 11th 2014. I was pregnant . but i lost my baby on 6th week. the misscarrige was on april 20th 2014. and the misscarrige is complete now . bleeding stopped on 22nd april 2014. how will i calculate my next ovulation date or period date. please help me.

    1. you have to skip this cycle and to get the next period date as very often a miscarriage is changing the cycle .. as soon you will get your next period on the first day count 12 days, start to have intercourse one day on 2 for 10 days. You will have more mature spermatozoids that way and increase your chance to conceive quickly. Good luck

16. My last period was on march 26 2014, and now my period is on April 30th. Its not regular sometime it takes 28 days sometime 33,35,30, like that… So I would like to know when will be my next ovulation. Which is the best time to get intercourse.

    1. On irregular cycle there is only one way to not miss your ovulation ! the first day of your period is the day 1 of your cycle. Start having intercourse on the day 12, then once every 2 days for in your case … 16 days. as your cycle tend to be long sometimes ! That way you will let your partner the time to build up more mature spermatozoids, they will live 72 h in the womb, they will be ready for your egg arrival ! Good luck

17. I delayed my period between March 29th and April 2nd.. Can’t remember how soon after I Came on my period but was no longer than5 days after. I’ve still not started this month and have taken 2 pregnancy tests that were negative?

    1. By now you should had tried another test no ?!. Stress is a very common reason to delay period, as travelling lot of overtime at work change in life style. it is to you to track down your intimate activity that was not protected and see if it can match your ovulation period to start to wonder if you are pregnant.

       good luck

18. Hi,I had my period April 18 to 25 2014 then me and my hubby had contact on may 6 and 10,is it have a possible that I get pregnant?

    1. Possible yes … depending of the length of your cycle and your medical history. If your cycle is regular you will know if your period gets late to do a test. But to be quite honest couple that are not trying to conceive are easily getting the good news as there is no conception stress. 2 contacts 4 days apart … there is a chance as your ovulation date is in average the 14 th day of your cycle that start by the day 1 of your period.

       good luck !

       1. Thanks…
          I’m still waiting my period now,
          Hoping that this is it.
          Almost 3 years we been trying
          To have a baby but theres no luck yet,
          ( Fingers cross)

          1. Hi I’m wondering if the OVULATION KIT can detect pregnancy? Because I’m 9th days delayed and I just have only a ovulation kit available at home so I try that then it comes possitive, do u think I’m still ovulating or do I am pregnant?
             Thanks…..

             1. that mean that you are ovulation an ovulation kit is not detecting the HCG the pregnancy hormone but the oestrogen that is raising when your fertile window arrives

                good luck

19. Hi. my periods are irregular for last few months because of stress. In January I had periods on 19th . then in Feb 23rd
    I traveled overseas in march. a lot of traveling and stress. I missed my periods and got on 1st of april.
    In May we had sex twice . around 10th may and sometime after 22nd may. I missed my due date that was 1st May. I was hoping i am pregnant but today May10th i got my periods . very disappointed 🙁
    my questions are:
    What would be my ovulation time. with irregular periods its hard to calculate.
    2nd how many times we normally have sex to get pregnant.

    I have a 4 and half year old boy with my husband.
    Thanks

    1. 10 april* and sometimes after 22nd april*

    2. the easiest way to calculate your ovulation day on a non regular cycle is to count the days from the day one of your cycle which is the first day of your period. From there your fertile period depending of the length of your cycle will be between the 12 th to the 18 th day. If you try to conceive I would recommend you to have intimate moment with your husband no more than 1 day on 2 from day 10 to 18. That will allow more mature spermatozoid to be ready for action !

       good luck

       1. Thank you so much

20. My last period was on 30 March 2014, I’m always on a regular 28 day cycle, have not received my period to date, just awaiting the next one, bf and I have been ttc for a few months now but due to the contraceptive injection I last took in August 2013 and my dr put me on Ovral 28 which I stopped in Jan 26 2014, my cycles were regular after that, its the first time I miss a period. Took a hpt at 5 days of being late but it came out negative. Last night I was suffering with bad pelvic and back pains thought period is coming, used a pad but still nothing. Have this elastic sensation though near vaginal area. Not sure its the after effects of intercourse because bf and I had sex yesterday (Sorry TMI). What is happening with my body truly?

    1. everyone have different symptoms and sign when finally getting pregnant , desiring so much this pregnancy might also making you listen a little bit too much to your body ! Relax and let the nature do its magic. As you are regular it will be very easy to do another pregnancy test if your periods are delaying for a few days !

       good luck
