Hello all! Il get straight to the question. My husband and I were separated for a while and I made an awfulll mistake and had one night stand with an ex on sept 4th. My husband and I worked things out and got back together at the end of sept. We had sex sept 28th and the beginning of october. I had my period inbetween the two men, starting on sept 23rd. I am beating myself up about the paternity. I had a ultrasound on nov 4th and I was 6 weeks, making my due date 6/30, which matched up perfect to my lmp. I then had another scan on dec 6, and it said I was 11 weeks, moving my due date to 6/26. Only a 4 day difference but alot to me. And I also had a scan at 19 weeks, still confirming a 6/26 due date. I am so scared and worried andj know my husband is too. Theres a 3 week window in the one night stand and my husband! I need answers please
