Hi. I have a bit of a concern. I had a medical abortion done three weeks ago. The bleeding was really heavy at first, but then it slowed down. It has been almost four weeks now and I'm still bleeding, but the bleeding has gotten heavier again and it has turned into a bright runny red. The runny bleeding started about a couple of days ago and it would stop for a little bit and this evening it returned. It has been so heavy that I have been bleeding through pads and tampons every 20 minutes or so. Could this be really serious?
