I had unprotected sex two weeks before i got on the patch the I had sex with me which is now my boyfriend just now told that he had cummed in me twice one that night and half loaded in me in the morning. which I was unaware of. two wks later I get on birth control that is the patch. I'm am starting to throw up now which has lasted about two wks now. I started the patch on july 11th. my breasts are starting to ache and I'm throwing up everyday. my doctor told me that was common in using the patch in the beginnign. but I thind I need a second opinion also I'm starting to slightly cramp every other day in the past week. %-)
