Unexplainable pregnancy tests

Elizabeth

I had surgery to remove right ovary and Fallopian tube along with pelvic flush . Then told by my ob doctor I should be able to conceive with no issues. I had a positive pregnancy test last May but must of had a chemical pregnancy. And I do I have endometriosis not sure of what stage she never told me and I didn't know anything about it. I've had many positive pregnancy tests yet nothing comes about them. And I have a period. So idk what is wrong with my body. I do know I had extremely high CA 125 levels than had blood work it had went down after the surgery but it was still not in normal range. So maybe that is causing the positive pregnancy tests? Idk what to think , but could they be throwing off positive when I could be having issues going on still ? Thanks everyone .
