Missed period on bc pill

Jada

So I’ve been on the pill for about three years now. I’ve always gotten my “period” during my placebo week, and it has always been on time. The past two months I haven’t gotten my period at all. I thought maybe last month was just a weird month and didn’t think anything of it. But now that I haven’t had a period again this month I’m starting to worry. Is this normal? Could my birth control have stopped my period after taking it for this long? I’m scheduling a doctors appointment but I figured I’d post here to ease my mind in the meantime.
