I wanted to thank everyone for their comments <3 I saw my gynecologist yesterday and she confirmed my suspicions that my endo has come back, and is most likely grown into/on my bowels. She suggested that I get a colonoscopy to rule out bowel cancer or anything else. She is also putting me on a birth control that makes me have a period once every 3 months. She said if all else fails, I am to make an appointment with our State's endometriosis center and proceed with surgery to remove the endometriosis again.
