I've been taking Yaz for the last 5 months. Last month I had unprotected intercourse (aside from the pill) but three days after I got my withdrawal period (it lasted 7 days). It has been exactly four weeks since that period, and I'm already on my placebo pills and still I haven't gotten my period.

Maybe I'm being paranoid since I've never missed a pill but I'm to scared to get a pregnancy test. Should I be worried?
