I had bleeding during this pregnancy and was scared to death. It wasn't light bleeding either, it was just as heavy as a bad period. I feared the worst, but then had an ultrasound and discovered everything with the baby was fine. It turned out I had a sub chorionic hemorrhage which is very common in pregnancy. I was put on pelvic rest which means I can't do anything that causes uterine contractions. No sex/organisms, tampons, baths, douching, exercising, heavy lifting and so on. I have read and know of people who bled during their pregnancy and went on to have healthy babies. I wish you the best and hope everything is okay.
