Steffy, please – my last period was February 29, 2016. I have done the pregnancy test and it came out positive. Please can you tell me how many weeks it is and which particular day that I conceived.
You are 7 weeks pregnant. It is possible that you conceived on March 14.
Hi my period was due on the 18th April 2016 it’s on 3 days waiting now and nothing yet. I had unprotected sex during my fertilized days. Is it possible I am pregnant!
I had my period on march the 5th and also March the 30th and that has never happened to me – two periods in one month. I haven’t gotten it in April and today is April the 19th and my nipples have been hurting for 4 days straight and that also never happened they never hurt. Can I please get some advice?
It is okay to have two periods in a month if they are more than 21 days apart. Your last period was 25 days apart – this means you had a 25 days cycle. If your cycle does not change, your next period is due on April 24. Wait to see if it will come.
Okay thank you me and my husband have been trying so hopefully it doesn’t come. 🙂
Hi. My last period last month is March 16, 2016, but in the 6th days of my period, March 21, 2016 I and my bf had sex. Is it possible that I got pregnant? I expected it this April 13 – but until now I don’t have a period? Please help me. What can I do?
You were fertile during March 28,2016 to April 01,2016. You have a 28 days cycle. You’re not likely to be pregnant but you can take a pregnancy test to be sure.
Hi..my last period was march 20-25. I had sex march 29,30,31 and april 1 in the morning. I am taking contraceptive pill from march 24 to april 1 then i stopped and didn’t take anymore. Then i bled after 3 days and lasted for 4 days but then it wasn’t my period. It was only because i stopped taking the pill on its half pack. My cycle is 28 days, I am supposed to have my period april 17 but it didn’t come, took a PT but it says its negative..but then i have a little stomach cramps, my breast tender and sometimes sore and my nipples are tingling sometimes and now my head is spinning..Am i pregnant?
Hi May, stopping contraceptive pills may throw the period cycle off. So it’s most probably because of that. But, to be on safe side, do take a pregnancy test after two more weeks. Right now it’s too early to take a test. ATB!
I haven’t had a period for March. I normally have my period start on the 18th – 21st, no later. It goes for 14 days. It’s now April 18 and still no period but already been sick to my stomach.
If you’ve had unprotected sex during your fertile days then you may be pregnant. If not, then your period may be late for other reasons. You can get the most accurate result if you wait at least one week after missing your period before taking a pregnancy test for confirmation. In addition, the result might be even more accurate if the test is done first in the morning as the urine is far more concentrated at this time.
Hi. I started my menses on the 7th of February and finished on the 11th. Then it did not come until 29th of March and finished on the 1st of April. Question: when will I ovulate as we want to have babies? Thank you
I’m seeing blood two days before expected date of next period
I had my period on the 16th – 18th of March and I ought to start my period for this month by 13th or 16th but, I haven’t seen anything of such till now, and I had sex with my hubby several time. Could it be that I’m pregnant?
I have six years baby boy l want to get pregnant again but is not coming what should I do to get pregnant again
It was supposed to start on march 15 2016. It’s already march 17 2016 and I still haven’t started. I’ve been cramping before 15 of march and still nothing. Took a pregnancy test on the 16 of march. It was neg so what could be happening? I always start on time.
Hi Ceci, 2 days are very less time to worry about. If you have not got your period till today, then take a pregnancy test. Pregnancy tests might give inaccurate results if you give them too early. So it’s best to wait 10 days after your supposed date usually.
Hi i had my period from march 20 to 25 2016 and have unprotected sex with my bf the 26th and my expected period should be today. Can i be pregnant?
I last had sex April 2 and my period should be at April 9 but still not having my period today, I’m experiencing abdominal cramping for 4days, I’m regular 30days cycle..
My last day of menstruation is on the 5th of April which days can I have sex to get pregnant.
On the 17th, 18th and 19th.
Hi, my period was March 22 and my last day was March 28. We had intercourse on the other day (March 30, 2016). We were not wearing anything and I was really wet. There was no pre-cum and he peed before we had intercourse. He didn’t come on my vagina, he just come on my boobs. Is this safe? I am on 28 a day cycle.
Hi Lakiy, If there was absolutely no contact between penis and vagina, then it’s safe. Just remember, even if one sperm goes in the vagina, pregnancy can be there. ATB!
I had sex on the March 20 with one guy and we used a condom . I had sex with another guy on March 26 unprotected and he said he finished in me. I’m a week late. Took a test came out positive I’m hundred percent positive it was the second guy. Or am I wrong?
