Good to hear that the bleeding has stopped, good luck for your BT tomorrow. I'm sure you'll be fine. When I had my mc I had quite a lot of constant bright red bleeding and strong early labour-type cramps that started with the bleeding. I think you'd really know about it if it was going to be bad.
Maybe I'll get some HPT's and do those every few days just to give me some peace of mind. I guess I'm only 6 weeks on Thursday so it's still early for symptoms. A bit of nausea would make me feel better somehow though!
