I saw an OB on Thursday, and was 5w5d. She did an ultrasound, and said she wasn't sure if there was a heartbeat...isn't that too early to get one even on an internal ultrasound?? She referred me for another ultrasound, but they didn't take my insurance. She also said I was nearly 7w...sorry honey, I was there, and trust my estimates more than hers! And yes, I've now found a NEW OB.
