I went to the doctor the other day believing I was 5 weeks pregnant based on what I thought was my period. I told the dr I had exposures such as X-rays of my knees, 7 nights of alcohol-usually 1 drink but two nights could've been 4 drinks at most( I had a margarita and domes there are 2-4 shots in those drinks), I took one hydrocodone on two different night and I sat in a jacuzzi for 45 minutes, and I was training for a half marathon. My dr said there were no red flags..,also, she said it was to my advantage that I was so early. She performed an ultrasound that day to confirm gestational age; she said it may be two weeks before she sees heartbeat and embryo. Well, guess what? Ultrasound shows everything: embryo, yolk sac and heartbeat of 111. Now, I am uncomfortable, but dr said she is not concerned at all. I have been pregnant four times in the past and all ultrasounds were on target. I am concerned that the bleeding I had was not a period, but uterine bleeding. It occurred after intercourse, was bright red with some clots and only lasted 3 days and there was also brown blood. I am concerned this baby is three weeks behind, not one week ahead. Shouldn't this dr have some questions about iltrasound since I had exposures? My cycles are consistently 28 day. Finally, when I told her my last period was normal, she said she didn't care; she is using the ultrasound date.
