According to my LMP and my positive HPT I was led to believe I am 9 weeks pregnant. I was having some brown spotting yesterday and the OB had me go in to get an ultrasound. Based on the ultrasound they said I am more at 6 1/2 weeks rather than 9 weeks. They did see the heartbeat, but did not tell me the rate or anything. I am just wondering if this is common, or something to be alarmed with.
