Thoughts ???

I’m on birth control, the pill, but this past month I slacked. Some days I missed taking it so doubled up the next day and that would go on for days at a time, 2 pills one day then none the next then 2 pills and so forth. Obviously I’m sexually active lol. My period was supposed to come 2 days ago and this morning I woke up to this. It’s only there when I go pee and wipe, it’s not a constant flow. I haven’t tested yet but I need some opinions on what to do??
