I will be 20 on the 16th of jan. and I sometimes find pain in my lower right abdomen. I have been reading about it. I am not pregnant, I am just starting my period. it doesn't feel worse doing anything itll come and go. this has been happening on and off since I started to gain weight. again, not pregnant. I have no loss of appetite or neausea. I do have irregular bowel movements. No fever and no pain when I pee. I just wanna figure out what it is, its kind of an annoying pain. thanks.
