Endometriosis?

[blondlox]

For the past of couple months, most of the time after having intercourse, I have been experiencing mild bleeding/spotting that lasts a few days. It doesnt happen 100% of the time and there is no pain with intercourse. Also, I have regular periods that last 7 days. I just read that a symptom of endometriosis is abnormal spotting. Does anyone else experince my symptoms or have endometriosis and can shed some light on the topic?

Also, I have had IC for 2 years now and am wondering if that contributes to this.
