This is my first time ever taking birth control (apri) my doctor recommended it to regulate my irregularly long periods which would last up to 12 days at a time and spot in between, and im in the first month and i just took the first sugar pill and i haven't gotten my period. I was wondering if it's normal for it to take a couple days to start or does my body just need to get used to the pill... I am just scared i might be pregnant.
