What if I had diarrhea after taking my pill?

Having diarrhea sometimes will probably not affect how well your pill works.
Severe diarrhea (several times in one day) might affect how well your pill works. You should use a second method (like a condom) if you have severe diarrhea. You should use the back-up method every time you have sex while sick, and for the 7 days after you recover.
Still not working? Forgetting to take a pill, throwing up right after one, or having severe diarrhea are reasons why the pill has a 9% failure rate. If that it is too risky for you, use a back-up method. Another option is to switch to a method that requires less effort.
Try a different method: condom, implant, IUD, Ring.
