I was previously on yasmine pills and now I have changed to Daphne. I've been taking daphne for 2 months and I skipped my first period on it. After taking the second cycle of pills I stopped it on tuesday and had sex on the friday (without a condom). I usually get my period 5 days after I stop the pill which would be sunday but its now tuesday and still nothing. I've had some cramps but no blood. Should I be worried?
