Super nasty I KNOW! But mucus plug or no??

So I’m 40 weeks and 5 days😭 I went to labor and delivery yesterday because I thought I was having contractions but they were irregular so it was nothing and got sent home. They checked my cervix while I was there and they said that I might bleed a little and that it was normal, which I just thought was weird because it wasn’t my first time getting my cervix checked and I never bleed when my obgyn did. But anyways, so I spotted bright red after going to the bathroom right after getting checked and every sense then I’ve had a brown spotting I think. Is this my mucus plug?? So sorry because I know it looks like shit 🤦🏻‍♀️
