Well I'm confused. My LMP was July 21st. I got a BFP on August 19th. Today I went in for the first U/S and according to that I'm 5 weeks, not almost 8!!! I don't get it....I shouldn't have been able to get a BFP in August right? Week 4 is barely when hCG can be detected...right? I'm so confused...my next Dr. appointment will be in two weeks, I hope she has an explanation for this.
