Pill spotting maybe pregnant

So I’m on the pill and my period finished on the 8th December and while I was in the bathroom I saw in my underwear there was a little spotting so I wiped and I saw light light light light blood and I checked again and again .... yes my partner and I are currently sexually active we’ve been together for 3 years ... could it be just because of the pill or pregnancy signs mind you I’ve been on this level pill for 2 years as I had to change the level ...

Could I be pregnant
