I use birth control pills but had antibiotics and I have a breakthrough bleeding. How can I stop it? In 2 weeks I'll have to take the placebo pills.

Unlikely:( Hi SzterW377, Unfortunately this is a common side effect of antibiotics when taking birth control pills. Unless the bleeding is very heavy ( changing a pad an hour) then it is best just to continue talking your birth control pills as prescribed. I also recommend that you take additional steps to protect against pregnancy, such as use of condoms. Of the bleeding is heavy, then see your doctor. .
