Last week I threw up around 4 hours after taking my pill and then the next day missed my pill completely. I had unprotected sex that following day and was spotting and thought it was just because I hadn't had sex in a while. I didn't realize I missed a pill however until Friday. So thursday I must have taken Wednesday's pill. (Hope that makes sense) long story short I decided to take plan b, should I be worried??? I've been on the pill for about 3 years now and never have missed a pill until not. Also not sure if me throwing a 4 hours later counts as missed. So then it would be two missed pills. I'm suppose to get my period next week and I'm not sure if I should be panicking or not. Help!!!
