I’ve been on junel 24 since July but I’ve been on some type of birth control pill since aug 2017.

On junel 24, my periods are getting very light. I was last sexually active on oct 23 with my ex and he used a condom and I tested for pregnancy in dec and I was negative. My periods are getting lighter and today I realized I still haven’t gotten my period and last month my period was only 2 days. Is this normal? I’m not pregnant, I know that. But I thought I would Atleast have some bleeding today and there’s nothing.
