Patient: Hello. My cycle is 28 days. On the 10 CD i had sex with a man, we used condom. On the 11,14,15 cycle days i had sex with my boyfriend,with the purpose to get pregnant,we dont use condoms. Now im pregnant. I donr know who’s dad of my baby. Please help me. I think my ovulation was on 13-14 day of cycle. I have read a lot that condoms are not very good to protect from pregnancy.
