I have had endometriosis for 4yrs and usually only experience bleeding during my period. I have pain during ovulation, but this is the first time I have bled during this time. It is more than spotting. It is heavier, and I am cramping and back pain, more like when I get my period. This is the 2nd day of bleeding on day 15 of my cycle. Is this normal for somebody with Endo?
