On the first week of pills (I've been taking them consistently for 5 months), I had unprotected sex on the 4th and 6th day of the pack. I took my pills consistently and abstained from sex but forgot my pill on the 2nd week (12th day of pack). I took that pill at 2 am the next morning when I remembered and then took the 13th day pill 4 hours late. I am still taking the rest of my pills consistently and not having sex. . Wondering if my chances of pregnancy increased.
