Could this be implantation bleeding?

Hi guys, so yesterday I had some bleeding after sex. I know its normal sometimes but it was very gentle, vanilla sex, no real cause for me to start bleeding. But i had unprotected sex while ovulating and my period isn't due for a week so it was odd?

I'm kind of worried because i also had uti symptoms 3 days ago and i still have a tiny bit of burning. But not nearly as bad as a few days ago so i dont think i have one.

All the minute clinics around me are closed where I am in California which is why i haven't gone yet.

So my mind is just whirling for what it could be. It was bright red in color, and later that night i had a tiny bit more.. but none this morning.

Thank you xo 🙂
