Is there a birth control patch?
The birth control patch is a combined hormonal contraceptive method, like the pill. With the patch, you put a new one on weekly for three weeks, and take the fourth week off.
If you had sex while missing two weeks of the birth control patch, you may be at risk for pregnancy. If you had sex in the last five days, consider using the morning after pill. You can restart the birth control patch immediately. Put on a new patch, and use a backup method until you've used the patch correctly for at least seven days.
