Hi, good day! Me and my girlfriend had unprotected last Sunday which is Oct. 28, 2012. We bought nordette and used it as an ECP. She took the 4 pills at 1:00 PM after the day we had unprotected sex(Oct. 29, 2012) and she took the other 4 pills at 1:00 AM(Oct. 30,2012) then after 4 hours she vomited. I am thinking that the effect of the pills is lessen because she vomit, am i right or what? Please advise, should she repeat the procedure i mean should she take another 8 pills? Thank you very much!
