I missed the 4th pill of my third week...I've read that when you miss a pill in the third week you're supposed to finish the active pill and throw away the pack and start a new one, skipping the last 7 inactive pills. But I continued taking the inactive pills and didn't start a new pack until I finished it I was scheduled to get my period the following week on wednesday and I did....but I had sex the following week on Tuesday Could it be possible that I could get pregnant ??
