5. Pain when going to the bathroom
Not all endometriosis symptoms are directy related to the reproductive organs. Even though the reproductive system is the most commonplace for endometrial implants to happen, in some cases they can be found in the bladder or in pelvic tissues such as the peritoneum. For this reason, endometriosis may have symptoms that are not directly gynecological. Some women with endometriosis feel pain with bowel movements and/or urination.
This could be a direct consequence of a deposit of endometrial tissue in the wrong organ, or a derivation of pelvic inflammation or an adhesion (which happens with the scarring produced by an endometrial implant induces the generation of connective tissue that sticks parts of the abdomen together, stressing all tissue around it). Even if pain during bowel movement and/or passing urine can happen any day of the month, you are most likely to feel this pain during your period, when the endometrial implants are most active.
