Ovulation bleeding?

Meme 👦🏽👼🏽👼🏽

Has any ladies ever experienced have been bleeding after sex? No period in July and No pregnancy wasn’t possible bc I didn’t have sex for like 6 months. I had sex August 2, The next day I started bleeding which I assumed it was my period but now my period is late and I’ve been having terrible acid reflux and some heartburn and a little bit of nausea. I am trying to wait it out before I test just in case my cycle start but I was wondering, has anyone experienced this and ended up pregnant?
