Irregular bleeding

Hey girls I really need help, for the last 2 cycles now I’ve bled after ovulation but before my period (aka the next cycle). I’m currently in between cycles again and had another bleeding episode however this one was different. It was during sex and it was a kind of thick pink, and it continued for an hour or so...any suggestions on what it could be??? I have an appointment on Tuesday but I’m so anxious cause I’m so cranky and so nauseous, I can’t help but think...but idk and I don’t want to get my hopes up for nothing...
