A member asked:

I just started taking triphasil (ethinyl estradiol and levonorgestrel) a week ago. after how many days would i have to wait in order to have unprotected sex without falling pregnant?

A doctor has provided 1 answer

One month to be sure: Birth control pills are generally effective after 1 week if started at the beginning of a cycle, however you should be able to be fairly sure that you are well protected against conception after 1 month. Using a back up method will help avoid accidental fertilization of an egg if you do ovulate during the first pack.
