I had unprotected sex on the 17th which was my second day of fertility according to my period calculator. Today is my 4th day of fertility (the 19th) and I took an emergency contraceptive (The Plan B pill) but I know those period/ovulation predictors aren't always right. I don't know if I'm ovulating or not and its my 12th day of my cycle and i should be ovulating around the 14th but it's a possibility I'm ovulating right now. Would the plan b pill still work if I was ovulating or could I still be pregnant?
