I took my pills as soon as i remembered this meant taking two pills on the same day.. i have had unprotected sex and my partner pulled out before climax.. i continued to take the rest of my pills as normal and have had my seven day break yet still haven't had my period.. i have taken a pregnancy test which was negative.. i'm now due to start my next pack of pills but unsure if i should wait to see if my period is just delayed with missing pills. what should i do continue taking next pack or wait??
