So I could be 4-5 weeks? I give blood again Wednesday! With DD my hcg was 91 at around 4.5 weeks. A little after 5 weeks we saw the teeny fetal pole. I can't wait until my u/s the 19th to get an actual EDD!!!! If I am right reading my O signs then I might have 0'd around the 22nd of May which would put me almost 5 weeks. I still can't believe we caught the first egg!
