I'm sorry you're worried - it's the worst feeling isn't it? I realy don't know what it means but I am hopeful and fairly confident that it could be implantation bleeding. I had that and at times it was very brown, quite heavy and even some redder bits. I thought I would m/c for sure but didn't - so there is hope!

See your doc again soon if you can to give you peace of mind. Unfortunately we can't fast forward to the magical 12 weeks and have the scan to show things will be okay. In this pregnancy I'm almost certain I will bleed cause I did with other 2 - hope not though.
