Pregnancy sign?

I used to bleed all through the depo shot, I only had one dose. It was supposed to be out of my system by the 26th of this month. I had Sex with my boyfriend the 28th and he got off on me it said I was supposed to be fertile that day.. We aren't TTC my fertile days wouldn't show up on my glow until the day after we had sex and I fixed it. I stopped bleeding the next day completely and haven't bled I have BARELY like just a dot of light pink clear fluid when I use the restroom. And I've had gas which NEVER happens but idk if I'm just being paranoid. VOTE PLEASE, or comment.
