been for a scan today and sat our bubba and his/her heartbeat nice and clear via vaginal ultrasound. but we went for early scan in the first place because I was spotting on and off for the past week.. some red some pink some brown. so with having had two miscarriages already I was concerned. but we heard peanuts heartbeat and that made us more positive. but since coming out the scan I've started bleeding bright red blood that is as heavy as a period in full flow. what does this mean :(
