On Oct 10,2009 I called a the pharmacist to ask about my orthro tri cycline lo pill I missed two dark blue actve pills on my third week and the pharmacist said to take two a pill to catch up. So on that saturday I took thursday and friday and then on sunday I took Saturday and sunday which was a dark blue and a green (non active pill) anyhow I didn't have sex for 7 days then I started a new pack of pills oct 18, 2009 and had sex twice probably thinking I should have been protected. Well my last period was early about 3 or 4 days (Oct 11, 2009 it started) and now i'm about 3 days late on my period is there a possibility that I could be pregnant??
