I am 6 weeks pregnant and bleeding brown, pink and even red blood for 2 weeks now. I had a scan and the sac was visible, then a week later another scan and there was a heart beat visible, the nurse said it looks good and has developed. She didn't explain though why I keep bleeding, all she said was bleeding is a threatened miscarriage. I wish it would stop, because its making me wonder wheather I'm at risk of losing my baby and its doing my head in. I didn't know you could bleed this much with bright red blood and still be pregnant, I'm due for another scan next week, just wondered if this is normal and what does it mean.
