I can say I am definitely not pregnant. Over the past six or so months I am having very irregular periods . Period dec no jan period feb and no period since feb. 13. I have cramps as if I am getting period, lots of acne (I never had this much as a teen. I also am unable to loose weight. (don't know if this is related. And I get up at least twice a night to urinate. Any help would be greatly appreciated.
