A member asked:

Dr. put me on a lower dose estrogen birth control due to breast soreness. is this lower dose less effective against pregnancy?

A doctor has provided 1 answer

Not at all: Birth control pills that are a combination of estrogen and a progestin prevent pregnancy through different mechanisms. Switching to a pill with a lower estrogen dose is intended to alleviate the side effects, while maintaining the efficacy of the pill.
