thank you for putting my mind at rest. i think i will ask for an early dating u/s when i see the obs next week. i just keep telling myself that if it is going to happen there is nothing i can do about it (ok, i'm a tiny bit of a control freak!) so i just need to relax. thanks again and i'm sorry some of you have had such bad luck - apparently m/c are very common but no one ever hears about it because the pregancy isn't announced until after 12 weeks!
