brockstar - similar thing happened to me and my OBGYN suggested an early u/s to determine the weeks.
When I had my post-op check up, OB did say he wanted to see me at 7 weeks, so I am just pin pointing that I o'd around 22nd, so in theory, that makes me about 4 weeks 1 day. I'll make the dreaded phone call this week and make an appt with him (last time I made the early call we suffered the m/c), so I'm a little apprehensive about it all! Will keep you all updated.

Hang in there girls, positive thoughts from everyone for everyone. March is the month! Go forth and multiply!!
