Stopped the pill, still haven’t gotten my period

Ashleigh

I had to switch BC pills because of insurance issues. I stopped the first brand on Jan 2nd and my period went on like normal ( a little longer than usual but I figured it was because I didn’t take a hormone pill the next night). However I have not gotten my next period and I can’t start my new BC yet because of that. According to my app my period is 16 days late. Just wondering if anyone else has experienced this and might have some insights?
