I have a big problem! My boy friend and I broke up around May 23, and I did a very stupid thing! I slept with another person(on the 26th). Somewhere arond this same time I should have started my period, so about the 28th I took a home pregnancy test- it came out positive!I went to the doctoer on June 4th and confirmed it and I estimated my LMP to be around April 20th. That put me at a due date of 01/25/04. Last week(07/24) I had my first sonogram and it changed my due date to 01/31/04, and put me at 12 wks and 5 days, and calculated my LMP to be 04/26/03. I need to figure out who I am pregnant from and how accurate the sonograms are at determinig how far along you are. Please help me figure this out!
