I am 27 yrs old. I got depressed when my bf broke up with me. And ended up sleeping with my ex. My problem is, (me and xbf)we had sex when i had a period. It was not my intention to do it on my period but it happened. My last period was on Sept 24 - 30. We had sex on 27th without any birth control because i thought it was safe. I just realized there's a possibility that i would get pregnant. Then, the following weeks, my boyfriend and i talked and tried to work things out. I can't remember the date when we had sex but i am sure it was 2nd-3rd week of October. I just found out that i'm pregnant on Nov. 4 when i took a pregnancy test and visited the OB. My doctor said she cannot determine how many weeks i was. So i will have to wait until my next visit on Dec 7 or on my 3rd month to have my ultrasound. It's kinda frustrating because my boyfriend knows that i am pregnant, and he has a little doubt, we used condoms but he took it off when he felt nothing, after that we had sex again but he did not use one anymore. He did withdrawal though. Was it safe or not? That happened on the same date on 2nd week and on 3rd week we used it again but he did not take it off. I am very confused and it bothers me every day. Whoever the father is, i still want to know. I am not worried being pregnant at all, in fact i am very excited! This is my first baby and im taking care of myself. Any opinions would be appreciated. Thanks in advance!
