Worried.

So I’ve been on the pill for a few months now (taking them on time everyday) and this week I’m on my placebo pills but on the 3 rd day I was bleeding old blood, and stopped. I still have two more placebo pills before I start my Active ones. I know this might sound stupid but I need reassurance, could be possible that I could be pregnant? (I don’t think I am but I wanna recheck)
