I went on vacation and i left my pack at home and so i missed the last 3 pills of the 3rd week. consequently, since my last active pill taken was on saturday and its wednesday i should have my period by now but i do not. also, i had unprotected sex in the beginning of the month and so im paranoid i might be pregnant, but i know its common to miss a period ifyou miss 3 pills in a row. help!
