I have been on birth control for almost a month now. I havw had unprotacted sex with my boyfriend a few times. I have taken a home pragancy test came out negative. I have read online that home test can be wrong. I been getting cramps off and on. Sometimes it makes me feel real sick. I don't really eat as much as I use too. I don't know what to do. I don't know if I should take another test or just go see my doc. Help me please.
