I'm on Yasmin. I know you're supposed to take it 21 days, but in the middle of that cycle, I dropped one on the ground and it being so small, couldn't find it. Instead of skipping that day, I simply took another pill and ended a day early, meaning, I took it 20 days. If I have sexual intercourse in the break period, will I have a high chance of pregnancy or am I pretty much covered???
