I need some advice on what this could be ?

Enazia 💗🥳

So my period is late by 4 days I had sex today and i bleed a little bit after sex it wasn’t dark red blood like a period would normally be. And my periods are never light they’re medium. After I cleaned myself I put a pantry liner on and well it’s currently 2:26 that I am making this post and there’s no sign of AF at all ! No spotting no nothing and I’m really confused 🤷🏽‍♀️ I looked this Question up and the only that keeps popping up is pregnancy 🤰🏽🤔
