My first pregnancy. I'm 36 weeks and 6 days. I had sex with my first partner on May 18th, my LMP was May 8/9th that month. My ovulation started the next week on the 23rd. And they said I was fertile May 20-24th. On May 31st or early that morning on June 1st I had attempted sex with another guy. He didn't cum as I seen but he did attempt to enter me but it didn't go in. After that we stopped. The doctors started my pregnancy on my next expected period June 6 and I was already two weeks on June 20. I'm very confused and I just want to know the truth. A DNA test will be took but can you guys help me? Please!
