Birth control.

Jenn

I recently got on a higher dose birth control, and am at the end of my pack. I haven’t taken an active pill in 3 days now, but I still haven’t gotten my period. I am sexually active, so pregnancy is a possibility, but I was wondering if the higher dosage could have somehow made it so I will not get one this one time? I was reading about it online, that when on birth control you can miss periods and so on. But is that true ?
