Hi Crystalilly. I had significant bleeding with my second pg at the 12wk mark and I was terrified I was about the lose the baby. I called the hospital and they said so long as it wasn't accompanied by painand cramping, then things were still looking very good for a viable pg. The midwife I spoke to also told me a few different reasons why I could be bleeding and that put my mind at rest a lot. I just stayed in bed for a day until the bleeding had completely stopped (it was heavy when it started and then it petered out to nothing within 24hrs of it starting). Luckily for me I had my nuchal fold u/s booked for 13wks, so I didn't have to wait long to see if the baby was OK, but I reckon I hardly breathed at all for that week as I was so scared/tense/nervous of what the u's would show. Never have I been so relieved as I was when the OBGYN picked up her heartbeat as soon as he put the wand to my belly. Turns out it was a bleed from the placenta but it had healed itself. She is now nearly 5.5yo and thriving and it might just be a coincidence, but she is also my most headstrong and defiant child.

Also, there is a great article on the main site about bleeding in pg (the main site is down temporarily, but check it out when its up again) and there is a chatter thread here for bleeding in pg too.
