Accuracy of transvaginal ultrasound
My boyfriend doesn't want to claim our child as his because I had sex with my ex last Sept28, 2010. But I had my period right after. We had sex (the dad of my son) last Oct10, 2010. I immediately had transvaginal ultrasound the moment I suspected that I was pregnant, which was last Dec16, 2010. The result shows that I'm on my 11th week and 2days of pregnancy and that I will give birth on July05, 2011. I'm sure about who the father of my son is. However, my Ob said that I was already pregnant last Sept. and that I will give birth on the 30th of June. This got my boyfriend confused, so he left me. This has also made me doubt myself. Isn't the transvaginal ultrasound the most accurate exam? Do I still need to prove to him that he's the father? Please help! :(
