I am about 3 months pregnant and just found out that I had bacterial vaginosis and an infected womb. I was prescribed two antibiotics that my doctor assured me were safe for me and the baby. I am now done with the antibiotics for the bacterial vaginosis and about half-way done with the meds for the infected womb. A couple of days after I started the medication I started to have a clear discharge with clumps of tissue in it. There was no bleeding, but I am having lower back pain and this tissue is still coming out. It ranges in size of very small flakes to clumps the size of the end of my thumb. I am pretty scared, but the doctors I have talked to say that unless there is bleeding, they don't think anything is wrong. Also, I have searched the web and cannot find anything on a human having an infected womb. Is this something I should worry about for the health of the baby?
