Hello, I'm 22 years old and my bf and I are sexually active. I haven't had my menstrual in almost 3wks as of Tuesday. I'm usual on time and have been at most two weeks late. I've been trowing up in the morning here and there and have pelvic pain and mainly stomach pain. I'm not on any form of conception. Not trying to get pregnant, but my bf and I are fine with it if it comes to it. I am just starting to have a little bit of brown discharge which is unusual to me. I have never been pregnant before either. I have had an ovarian cyst before, but haven't had these symptoms due to it. What should I do?
