I was DX with Endo after my OB suspected that's what it was. I was down right sick for over 8 months not knowing what was wrong with me. My cycles went all off whack when I turned 30. Up til then, you could set your clock by my cycles. I knew down to the portion of the day that I would start. my cycles only got worse and more crazy. Cramps to the point I was basically useless to my family, along with severe nausea every day. Horrible fatigue, depression, sharp pains in my abdomen, cramping throughout my cycle, especially after sex. Sex made me nauseous, which caused a huge issue in mine and hubby's sex life. I went to my doctor for months, running blood tests, ultrasounds and even a HIDA scan (injection of radioactive fluid that is monitored while it runs through your gall bladder, liver and kidneys) and all was "normal". So I finally went to my OB after my sister who has Endo recalled her symptoms. OB for sure thought that's what it was to the point of when surgery day came he said, "I'm gonna look everywhere because if it's not obvious, I'm gonna really have to prove it to myself that it's NOT endometriosis". I came out of surgery and the first thing hubby said to me was "He found it...it's endometriosis". I burst into lethargic sobbing (from the meds) because I finally had an answer. From what I know, it's different from person to person. My sister has it so bad that her C-section incision stuck to her uterus because she has it so bad, but she rarely has any type of symptoms. Me, on the other hand, have a mild to moderate situation, and I have HORRIBLE symptoms. Only surgery can really tell you for sure, but if you suspect it, it's worth a talk with your OB. Hope that gives you a better idea! Sorry it so much to read lol
