Okay I bet you guys get a lot of this - but I am just looking for opinions. Now, before I start I just want to remind everyone that we are all just human, and we all make mistakes. Anyways, my lmp started feb 22-25 but my first ultrasound said feb 22. My obgyn told me I probably conceived based on my last period, march 9th. I'm confused and I will tell you why. Me and my [then] boyfriend, were being very stupid & not using protection all the time march 1-14. I took the morning after pill march 13. We broke up, and I was just depressed - so I was invited to a party and got drunk for the first time (i'm 19), and slept with a guy. I know we used a condom but because we were so drunk - I have no idea how good it was used. Now, with that said... I've had some confusing dates from ultrasounds. My first ultrasound was at 6wks (obgyn) and the sonographer told me I concieved the march 5-8th, my 2nd ultrasound was from a pregnancy center when I was 10 wks, and said I conceived march 10, 3rd at 19 ultrasound from my obgyn said march 12, and my very last one this pregnancy I got from a pregnancy center (again) when I was 21 weeks said I conceived march 15. Doctor told me he is sticking to my nov 29th due date according to my last period & that early ultrasounds are more accurate - where later in pregnancy babies tend to go by there genetics so baby could just be measuring smaller (since im a small women baby could be short like me) now - with that all said... I know I will need a dna test done to be for sure, but who is probably the father?....(in your opinion). Thanks guys :) btw- i'm having a boy !
