I have PCOS and have severely irregular menstrual cycles. For the past few weeks I have been experiencing some symptoms. TMI ALERT!!! When I used the restroom a few weeks ago it looked like I urinated couple of small pieces of tissue it also happened a week later. Currently I am experiencing extreme fatigue, nausea, lower back pain off and on, lower abdominal cramping, and pressure/tug like feeling in pelvic area. These symptoms have been off and on for a few weeks. I took a pregnancy test this week and it was negative. Could this be gastritis or PCOS related issue.
