Melster, phone your Dr first thing in the morning and get a referral for a scan. They may be able to do it the same day. Maybe read some positive stories on BB re bleeding in early PG to try to reassure yourself tonight. I know how horrible it is. It is the most stressful time ever.
I know this is probably not going to reassure you much right now but my best friend bled for two weeks at around 7weeks and everything was fine.. She is now 25 weeks. Please try to relax. Big hugs. We are all here for you xx
