question: hello, ive been walking up with cramps and peeing hurts abit some times when i pee first thing in the morning. and my stomach had gotten bigger so much after i started taking birth control . i dont know how i am gaining so much weight i was a vegetarian for a month but i still gain up to 15 pounds.... is it the birth control ? or i have an infection in the bladder ? uterus kidneys ? somthing ?
