Spotting with 4 active pills left in 3rd month of birth control pills (junel fe 1/20)... have never missed a pill and have only taken it late once due to daylight savings time on november 3.... should i be worried about pregnancy?

Can test, if worried: If a woman is consistently taking combination birth control pills (every day) and has been doing fine on them for more than a month, she is protected against pregnancy every day. That protection doesn't change whether she is on the hormone pills or the inactive placebo pills. She can feel relaxed and not worry about pregnancy, regardless of when she is having sex, but she can still catch STD's.
