8 weeks light bleeding?

Toni

I am 8 weeks and got to see the heartbeat yesterday but have been lightly bleeding these last two days brownish/pink blood. Dr said cervix is closed, was able to see a heartbeat but uterus is tilted so it was hard to find the baby at first. My question is has anyone had bleeding and still had a healthy pregnancy? I had a miscarriage a while back so this makes me nervous. Thanks ladies!
