I had spotting (red) at 6 weeks, and brown discharge at 8 weeks when I was pg. the first time they sent me for an u/s, the secod time they said it must just be old blood and everything would be ok, which in my case it was and I now have a healthy 18month old son.

I hope everything is fine. Maybe if you are far along enough they might do a scan and make it your 11/12 week one?
