My cousin has been on birth control for over a year now. She just started last month having problems with her monthly, she was spotting last month and then it went away. Then she started to have bad stomach pains and her stomach looked like it was getting a little big, then the next day it went down. She decided to not take her birth control nomore, after she read the side affects. Now last night she was up all night with bad pain in her stomach and she was throwing up all night. She has taking like 3 pregnancy tests but they are all negative. Can someone please tell me what they think. Thank you
