Sooooo idk what’s up with my body lately! But I really need someone to help ME!

I had sex, bled a little bit not enough to fill up a pad super light pink, I was sure he knocked my period on early because usually if I have sex and I show a trace of blood, either a few mins after or in the morning my period would follow shortly. All day I’ve been wiping & literally not even a little speck of blood when I wipe or pee. Has this happened to anyone and they end up pregnant? Period due in 2days guys. Am I still in?
