I have been on Marvelon 28-day BC pills for 2 months. I was also on it 3 yrs ago and i would get my period 2-3 days into the placebo week EVERY time. I skipped the first placebo week of pills for a trip, and i took my last active pill on august 23rd. I have no period yet, and i have discharge that resembles that to ovulation- stringy and clear. I had unprotected sex on aug 9th and aug 20th and both of those times ironically i missed a pill by 12 hours (caught up in the night!) why am i not getting my period? should i be taking a pregnancy test?
