Febuary 22nd I took a at home pregnancy test that quickly stated my pregnancy to be positive. March 4th, first ultrasound and HCG level blood draw, with only faintly a sac seen so unsure how far along I was, my HCG level was 3,000, doctors stating I could be 2-3weeks or 4-5 weeks pregnant. Second ultrasound a couple days ago, baby and everything seen but still very tiny..stated I am six weeks and six days along today. My OBGYN had said I got pregnant on valentines day, due date November 7th 2009. The night before valentines day I did do the deed with my boyfriend, so that would be right, but she had also stated last day of my period would be January 31st, this I don't quite remember, but doesn't sound right. I believe my period was January 16th through the 23rd, and I did have sex on January 28th was the last time I remember having sex before around Valentines day. If I did conceive on the 28th wouldn't I be farther along than I am now? Is it possible I ovulated a little late, which would make sense, my last pregnancy I got pregnant the day my period was suppose to start. What do you think?
