I'm a 30 yo female. For the last month I've been steadily gaining weight up 10 lbs with no change in diet/exercise routine. I have pain/discomfort in my mid/low abdomen and have notice a changes in my menstrual pattern (however I'm on implanon so irregularities aren't abnormal). I also just noticed a ping pong ball sized bruise on my public bone area. Any ideas? I did see a dr Monday and might have not reported all my symptoms but I had a uti and was placed on keflex.
