Pregnancy Info HOME

I really need your help. I get my period every 10th of the month and it lasts about 3-4 days. On August 9th, Tuesday I had unprotected s_x with some guy and he came inside me. The following day, the 10th I got my period and it lasted its normal 4 days. I didn't use any tampons (which I regularly use) just pads because I wanted everything to come out. On August 21st, Sunday my boyfriend and I got back together and we had s_x and he came inside me. Later that week, the 27th Friday my boyfriend noticed that I was peeing a lot and feeling funny. September 6th, Tuesday I took a pregnancy test and it came out negative. I waited a week later to take another test. September 13th, Tuesday I took a pregnancy test and it came out positive right away. I just want to know who I am pregnant from. The other guy or my boyfriend. Since I had s_x with the other guy and got my period regular the next day, I released an egg. So he was not able to get me pregnant, right? From all my information that I have said. I hope you will be able to determine who I got pregnant from.I know it's my boyfriends, my now fiance. But I just want to make sure again. I'm really scared. This is 'our' first baby together and I want to make sure it's 'ours.' Thank you so much.
