So! Good news - we know it's not ectopic. But - I thought I was 6w4d, and I'm measuring 5w5d - of course it isn't like my cycles were regular yet... and I have no clue as to when I ovulated. We go back next Friday when we should see a heartbeat!
One hurdle over, one to go!
The other thing is - I'm not 100% remember when CD1 was either... maybe the 1st, maybe the 7th? I really wasn't paying attention. You know, because I wasn't thinking I could get pregnant on my own?!?
