If pregnancy is a concern, take a test. One would be accurate by now and you'll know if that's the cause or you can take that possibility out of the scenario.
Symptoms of endometriosis range from mild to severe. You may have many large growths with little pain. Or, you may have small areas with intense pain.
Cramping and pelvic pain (especially just before and during menstrual bleeding)
Pain during sex
Low back pain
Pain during bowel movements or urination
Your doctor will ask about your symptoms and medical history, and perform a pelvic exam. These are best done early in the menstrual period. Since you may not have any symptoms, diagnosis is usually confirmed with a laparoscopy . This test allows the doctor to see if there are patches of endometrial tissue and scar tissue.
Since this has been going on for several weeks and is not stopping, please seek medical advice.
