Please help me. I am 19 weeks pregnant. My last period was on 6/6 and I did a test on 14/7 that said I was 2-3 weeks gone. I had a scan on 30/8 that said I was 12 weeks and 1 day. Me and my fiance had sex most dat from 23/6-30/6 . I went out on 6/7 and got very drunk. I had a conversation with my boss in a side corridor of a bar but there would have been people coming and going. I think we had an argument and I may have said something flirty to him. But he called me a taxi and threw me in it. The problem is I keep worrying that I could've had sex with my boss and got pregnant by him or the taxi driver who took me home and I don't remember. I'm going out of my mind with worry and so scared I won't know who my baby's dad is as I have no idea who the taxi driver was. I can't eat or sleep I'm not bonding with my bump and my fiancé is finding if hard because I'm crying and worrying about this day and night. I feel like killing myself. This started because I have irregular periods and was checking to see if the scan could be a bit out but it has spiralled out of control. Help me!
