I had my last period on the 10th of March. Now I had sex on the 27 of March and we checked the condom and it wasn’t broken but last Saturday night we had sex as well and the condom broke so Sunday I took a morning after pill but I didn’t have my period yet. I’m so scared to be pregnant now can I be? What do I have to do now?
The morning after pill may have delayed your period; you may not be pregnant. How many days are in your menstrual cycle? When is your next period due?
Normally like 30 so I’m 5 days late I did a test I’m and it was negative but still don’t have my piriod
Sarah, most probably the pills must have delayed the period. Also, pregnancy test should be taken after at least 10 days of missing a period, for better accuracy.
If my menstruation starts 12th of March & lasts 4 days while the next period starts 10th April, how do I calculate the length of cycle?
You have a 29 days cycle. To get this number count March 12th as day 1 and do not stop counting until you get to April 9 – you will count 29 days. So it takes 29 days before your period started again on April 10.
My last period was march 14th-18th 2016 but they are usually irregular and I had unprotected sex on easter march 27th 2016. I have been experiencing a lot of cramps and back pain and I have felt bloated for a week and a half straight. I took a pregnancy test April 10th (the 5days sooner riteaid brand), it was negative. Could I still be pregnant?
Hi Shay, you can try taking a pregnancy test after 2 weeks of first one, to make sure, if you have not got your period till now. If it is still negative, then consult a doctor. ATB!
My last period was on Feb 26 then the next menstruation was on March 30. How many days are in my cycle and what is the best time for getting pregnant. I’m celebrating 2 years of marriage and I want to have a baby.
It is possible that you have a 33 days cycle. All things being well, you’re likely to be fertile from April 16 to 20. Your next menstrual period is expected to start on May 02, 2016. Good luck.
Your next menstrual period is expected to start on March 30,2016.
You next most fertile period is March 14,2016 to March 18,2016.

Hi Amanda, please see a doctor and take a blood pregnancy test. All the best!
Hi, my last period started March 7, 2016. I am 4 days late and I am having frequent headaches and nausea. I did a home test but it was negative, when should I try and test again?
You need to re-test at least one full week after you’ve missed your period. Wait a few more days.
Pls my first day of my last period was on 15 march 2016 and the last day was 18 march 2016.I had sex on 25 march 2016.can I be pregnant?
Hi Ayebea, yes there are good chances. But please wait till next period before reaching any conclusion.
My last period was on 31 March to 2 April 2016, my ovulation starts on 22 to 27 April. I had sex with my husband on 10 April, please when is the right time to get pregnant?
The most fertile days in the cycle will be at least 3 days before, during and some days after ovulation. This will be the best time for you to try and conceive. Sperm will survive for 3 to 5 days while the egg will last for 12 to 24 hours. You are fertile for about 5 to 7 days.
Hi Emily. My name is Manita. I expected my period April 7 2016. I am now 3 days late. I felt like my period was coming but it still hasn’t. My period is usually like clock work. This morning I went to the bathroom and when I wiped blood was on the tissue. I figured I had started but no blood after that no trace or sign of blood. Could I be pregnant. I’ve taken approximately 10 pregnancy tests which were all negative. I have 1 son he’s 4 and when I found out I was pregnant with him, the situation wasn’t anything like this (unpredictable). Please help, I’m very in tune with my body now. I’m questioning if I really am. I’ve been feeling bloated like I’m coming on for about 4 days but no period. I don’t know what to do. Please help. Isn’t it too late for that blood to have been implantation? I’m so confused. Oh BTW, we are ttc but never expected this.
Hi Manita, pregnancy tests are recommended to take around 10 days after your supposed period date. So you should take one pregnancy test now if you have not got your period already.
Pregnancy signs might vary greatly with different children as it depends on many factors (first pregnancy/age/food habits/mental and physical conditions etc). All the best!

Comment Text*hi..i
I had my last period on 23-25 March. On 8,11 I had sex with my boyfriend and then again on the 21 and 22 March. And last month(March) I didn’t have my period. I was feeling tired and sleepy for a few days after that and my breasts were fuller. On 3-5 April I had my periods and today(9) have been having cramps feeling funny.i never took any test when I got my period.what could be the problem,m I pregnant?
Hello, if you are sure that you had proper period during 3-5 April and it was not some other kind of bleeding, then most probably you are not pregnant. Are you having any other unusual experiences too?
Birth control might be a reason here. If you are still feeling cramps, please see a doctor. All the best!
I had my period the 21st of July which lasted 7 days, on day I had pull out method sex. I got back with my ex on the 2nd and had intercourse unprotected 3rd, 4th,5th , and 6th. Chances of pregnancy from sex on day 8?
Brady, sorry your question is not very clear. If you are pregnant and want to know on which date it happened, there is no way to know that without a medical test.
Had a light period on the 18 th feb 2016 then had another period on the 5 th March notmal one this time had a few headaches been sick and white milky discharge 5 test negative what should I do next thanks x
Hi Sarah, have you got your period in April by now? If not, then please take a pregnancy test again. All the best!
Hello I am 6 days late and my last period was March 3, 2016 and i took 6 days.
Please i wanna know if i am pregant..
Hi Hannie, 6 days late is not uncommon. Please wait for 4 days more and then take a pregnancy test. Late or missing periods can be because of many reasons other than pregnancy too- like a new medication, a sudden change of diet, heavy exercise etc.
I had unprotected sex on 9th March and after I missed my periods on 20th of march, I tested four times and two of the were negative… Home tests were positive…I again got my periods on the 3rd of April which are heavy and cramps for five days now…. Could I be pregnant or what could be happening to me?
If you’ve tested positive you need to start booking visits to your OBGYN. It is possible to be pregnant and still have a period. You must see your doctor.
