so i’ve been on the pill for a little over a year and I usually start my period on wednesday of my placebo week, pretty much without fail. it is wednesday of placebo week and I still haven’t gotten my period... i am kind of worried. I take my pill PERFECTLY and also use condoms every single time I have sex, which is admittedly often. but I use double protection. should I be concerned that it’s not here like it usually is???? if not, when should I be concerned?
