I had a surgical abortion on April 6 and I bleed for 3 1/2 weeks I had sex one time on May 10 unprotected... May 21 I experienced some bleeding with mild cramps it's been 6 days now the bleeding is mild not enough to fill a pad but I do wear a tampon when I take the tampon out its brown and red blood not heavy at all covers about 60-70% of the tampon and it's on and off like in the morning when I take the tampax out it will be a very little bit of blood on the top and through out the day it's mild and also with the bleeding I been having back pain as well right along with ongoing headaches what is these symptoms???
