  1. hi there,

    pls my period came on the 18th of june and ended on the 22nd. had unprotected sex on the 27th which make 5 days after my period. can i get pregnant that way? also this month of july my period is yet to come.

  2. Hi there, I’m 25 married,trying to have a baby,my period is always late or should I say always change the date to start or finish but it’s always there in every month,I had my last period April 18 to 25,me and hubby r always had a contact,then June I don’t seen my period but I had a spotting first light brown then goes dark brown 3-4 days,I went to doctor for blood test it comes neg.and my progesterone is low,and now July I don’t have a period again,I done my ultrasound last year and there’s nothing wrong with it,any suggestions that may helps me? Thanks appreciate..

    1. Since how lng are you trying to conceive ? if it is more than a year maybe you should consider a visit into a fertility clinic to make sure nothing is wrong on you and him. Also for person like you that have an irregular cycle the fertility window is day 10 to 17 of your cycle. Day 1 being the first day of your period. During that window have intamate contact only one day on 2, to allow more mature spermatozoids to be released.

      Good luck !

  3. My period is calculated 26 days before now is calculating 21 days. Please, I hope there will be no problem with me.

    1. There is no problem with you , periods are following your hormonal flow, you can be regular for years then turn irregular for some reasons , nothing being wrong. If you have worries plan to speak with your gynecologist at your next annual visit.

      Good luck

  4. hi,
    I gave birth to a baby boy, and got my first period just after he turns one year and one month. I am thinking of using SFM or calendar method of family planning, is it possible to start using it already or should I wait for more months.
    Thanks in advance.

    1. The calendr method is only 74 % accurate if you have a regular like a clock cycle. I you do not want to conceive again in a short lap of time I would recommend you to use another contraceptive method.

  5. I saw My period on 8 of july and I had sex on the 26 of july will I be pregnant ?

  6. Hi I last had my period on the 28th of june. For this past week iv had 4 days of cramps like period pains. And now nausea and diarrhea( sorry tmi). Im worrieddddd. Me and dh had sex but we weren’t trying for a baby. Are these pregnancy symptoms or something serious? ?

    1. personally, i have all these symptoms to every period I have … unless you have a positive pregnancy test in hands …. Has you had your periods …. you should not be worried

  7. My period came on the 25th of June then light spotting on 19th of July. what to think

    1. Hi,
      would be pulled by the hairs but yes, as spermatozoids can live 72h in the womb … and that the egg can be fertilised early in the tube.

      good luck

  8. I had my first period on June 21 2014 after having my baby in april.i haven’t seen anything since then . should I be worried. COULD I BE expecting again

    1. Hi , give your boby a bit of time to recover from your pregnancy the first few cycle can be irregular and completely skipped. Tiredness new life routine .. getting back to the gym to get fit after the delivery are all good reason for your body to skip a cycle. In case if doubt a blood screen test will not lie and clear your mind of all possible doubt

      good luck

  9. I’m a mother of 2 kids boy (2 years and 8 months old) and girl (9 months), I went on my period on the 06 July till 12 July, had sex with my husband to be on the 20th July and the condom burst,on the 28 July i got my period again. I might be pregnant or not? . we don’t want kids now, since we’re planning to get Married anytime soon.

    1. Hi , if you had your period on your regular scedule I would no be worry but you realise that knowing that the condom bursted … you could had use an emergency contraceptive method to avoid all this wonder. Maybe you should also consider another contraceptive method to use with your condom, as contraceptive pills or spermicide mousse.

      good luck

    Midnight hungry & thirsty. I always woke up @ 2 plus am. Slept around 3plus am. i cant woke up in the morning. Feeling to continue my sleep again. My whole body is aching. My waist also painful. Am i preganant? Pls advise…..

  11. I had my period on 26th of july and it finished on 30th of July when will my ovulation start?

  12. Please,I had my last period on the 10th of July and made love from 21st-26th. Do I have a high possibility of getting pregnant???

    1. Hi! in a regular menstrual cycle ovulation usually comes two weeks after the last period and it seems that’s the time you made love. there are other signs that could point to ovulation and you can read more about them in this post.
      if you didn’t use any protection there’s a high possibility of getting pregnant. I’d suggest that you use a pregnancy test and be sure to use protection next time, if you’re not planning to have a baby yet

  13. Hi

    My last period was on June 30th for 4 days or so and I was expecting my period around August 1st and still have not got it. I took 2 pregnancy tests and all said negative. I’ve had what I thought were PMS symptoms but now I’m wondering if they could be early pregnancy symptoms. Should I wait a little longer and test again?? Or will my period come

    1. Hi ,

      some change in your routine can delay your periods or even completelly skip them … gym sessions, new job, stresses of all kind. With 2 tests done , being late on your regular scedule … I think that you are pretty fixed that i might not be a pregnacy but if you are still doubting do another one, if you skip another cycle I recommand you to visit your family phisician.

      Good luck

  14. Hello, I had unprotected sex on July 15th, a day after my period ended. My period that month was July 10th – July 14th. I used this period calculator and it said I should’ve had my period the 7th. But so far, I have not had any signs of a coming period. Latley, I’ve been having these white clumps come out when I go to the bathroom. I also have been having diarrhea.
    Could I be pregnant?

    1. Hi , It is rare but you might had a double ovulation, do a test to determine what is going on … this is the best way to verify if you are pregnant or not.

      Good luck

  15. Hi, saw my period on the 20th of june n ended 24th june. Had unprotected sex on the 28th june, 5th , 8th n 16th july. Can I get pregnant?

  16. thanks! i put my fears aside and went ahead and took a test about a month ago and it turns out that i am indeed pregnant. I’m so excited, i”ll have my first prenatal visit in just a few days. Thanks for the advice!

  17. I saw my period on 29th of July and had sex on 6th and 11th of August can I be pregnant?

  18. My question is I have my last blood flowing period on 1st – 6th July.

    27th-30th July was to me a no period at all, im very confused 🙁
    On 27th of July I thought i got my periods (sorry tmi) I had lower back cramps & felt like my periods came on, but I only had brown mucus on my undies. For the following days till the 30th I had no bleeding at all no even when i wiped but I did have alot of lower back pains. I took a test Tuesday night & negative. On 30th july i went to the toilet wiped & I had a bright red blood spot so i thought my periods came back. Nope no bleeding … but i have been having period like cramps for the last 3 weeks on and off – weird

    Ive taken test which have been negative, so im alittle worried as to what happened, any info would be lovely

    1. Charlene, it sounds like you might be & I may be as well. I have an appointment with my Ob\Gyn & I will let you know the results. It sounds like we have experienced implantation bleeding when the egg fertilized. My girlfriend experienced the same thing & she is 5 weeks pregnant. She took two home pregnancy tests but they weren’t accurate. Good luck! 🙂

    2. Period cycle is changing in a women life… if it is a single experience I would no worry about that. Spotting is normal as the lower back pain that some women experience to a very high lever other will never have to deal with that. If it continue for another cycle .. you might take an appointment with your gynecologist in order to determine what is the source of this disconfort and light/absence of normal period.

      Good luck
