So me and guy #1 had been trying to conceive. On August 31 I found out I was pregnant. My lmp was July 24. I went sept 22 for a dating scan. It said I was 7 weeks 4 days. Guy #1 came in me every time we had sex. But on aug 17 I had a guy #2 try to have sex with me. He only put it in once. And I told him no. Cause I wasn’t on birth control. But the ultrasound said date of conception was July 31. I just wanna make sure guy #1 is the baby daddy considering I’m due in just a few weeks. Please help!
