Missed tues&wed pill, took 2 on thurs, had unprotected sex then took 2 pills on fri, last pill on the 21 day pack is sat. chance of being pregnant?

Absolutely!: Missing pills and then trying to "catch up" can certainly throw off their effectiveness. You can test for pregnancy 11-14 days after when you think you conceived (ie the day of unprotected intercourse). If negative, you may need to find a birth control that fits your life better. Definitely speak with your doctor if you have issues remembering the pill, because we have lots of ways to help!
