Navigating periods on BC

I’m on the pill and the past month or two I’ve used it to skip my period. This month I didn’t but I’m not sure I had one... there was one day I had a bit of dark brown discharge in the morning and had wiped a little bit of what I presumed to be blood later in the day. Nothing since. No cramps like I normally have either. If you have used your BC to skip a period and aren’t sure you’ve had a period, do you wait to start taking your BC again until you have one (or take a pregnancy test), or do you just continue to take it again when you’re supposed to? Not sure if I should give it a couple extra days or just start my next pack.
