From what I have just read hun it is very common and if it's only small you have nothing to worry about. Can you see if you can get into another OB sooner to ease your mind? 3 weeks is a long time to wait if it's worrying you
I'm ok. I figure the relief ob would contact me and get me in if it was a pressing necessity. Besides, if it was going to cause significant bleeding and a miscarriage (which inreally hope it doesn't) they wouldn't be able to do anything anyway this early. I'm just going to focus on the positives.

Thanks Em, and I hope you get a definite answer yourself very soon.
