Plan B is an effective way of preventing pregnancy after having unprotected sex. Usually, Plan B is taken as two doses 12 hours apart. Occasionally, a doctor
might recommend taking both doses at the same time (this sounds like what you did), and this is also effective although it tends to cause more side effects, like nausea.
However, it is important to remember that Plan B is not perfect. It prevents pregnancy in about 90% of cases, meaning that it does not prevent pregnancy in the other 10% of cases. For this reason, it is always important to follow up with your primary care doctor
or your OB GYN doctor after taking Plan B, as they will be able to rule out a pregnancy. Keep in mind also that a pregnancy test will not be immediately positive after having sex, so it may need to be repeated in a few weeks.
Your doctor will also be able to provide you with additional advice about how to prevent unwanted pregnancies. Unfortunately, condoms are one of the least effective methods because they can break, slip off, etc. If you want to have more security than that provided by condoms, your doctor can discuss the other contraceptive methods available to you (in addition to the birth control
pills which you have already tried).
