... pills in one night so I continued to take the rest of my pills as scheduled. However, I started the new pill pack the day I normally started it( which is a Monday) Which means I had one extra day of my period since my pills were off schedule. But since I have 4 inactive pills only-I still only had my period for 5 days. I'm 10 days into the new pack now but had sex on the 5th day. I'm worried because I think I should've started the new pack the day before on Sunday? What does this mean as far as effectiveness goes? Could there be a high chance of pregnancy(I know there's always a chance no matter what). Any help would be great
