Hi Ede, the probabilities of getting pregnant while on your period are low, but they are not zero. Sometimes the sperm can live inside you for 2-4 days and then you can conceive 3-5 days later. Have you got your period by now?

Hi Amaka, it should be 6th Apr. You should try on 5th to 7th Apr to keep the chances even higher. All the best!
I was always told that you have to have at least two periods before you do the actual calculating. For instance it is the third month of the year. I thought I had gotten pregnant because my period showed up on March 24 but I expected it to be on the 23rd of March. When I put the total number of days between my period being the length of 26 days the period Caculator said that my period should have came on March 20th. I used the period calculator over and over again it said my period was supposed to arrive on March 21 this time but that is a total of 26 days. 26 days from February 24th and January 29th. So the first month-to-month was right and you need to be counting from the first day it began with notations on the day it stops. To me spotting doesn’t count. For instance I was correct that it is a total number of 26 days in between January 29 and February 24th my period came on March 24.That means that the length between days of my yearly cycle is going to be 30 days. So I expect my period. From now on to arrive like clockwork the 24th of each month I was told that Everywoman needs to be writing down her period snd studying the ovulation days that is how you prevent a pregnancy but I have gained a new found knowledge that the guy I was with told me he had took the rubber off and he should’ve told me that he came inside of me so it baffles me and I wonder how did he know my fertile days the days I was fertile were the days I had sex with him so I do believe that science is getting closer but sometimes it is just goes to show God knows what he is doing and any guy or a particular partner in your life if he really wants a child then he will come into your life and stay
Hello the first day of my last period was the 3rd feb it is now the 25th March I have been having unprotected sex should I be worried advice needed please
Hi Rachael, I would suggest that you take a pregnancy test. And remember, unless you want to try for a baby, never go for unprotected sex. Even a single time can result in a pregnancy.
I got my 1st period on 14 feb. then 25 – 27 feb. I have sex with my bf, then 28 feb. started my fertility, 29 feb. I got sex with my bf but before we got sex I take my 1st pills. Its is possible I getting pregnant?
Hi Rose, if you have used pills, chances for pregnancy are low. Are you sure that you got your period on 14th feb and then on 25th? That’s a very short period cycle.
I had my period on 2nd March 2016 and had sex with my husband on the 15th of March. Is there a chance of me getting pregnant?
Hi Marie, if you have a regular period cycle of 28 days, then yes you have a high chance. If not, then still you have a chance, as sex at any day can result in pregnancy. All the best!
