Early ovulation ? Implantation spotting ?

Period ended 6 days ago. Now my cycle has always been irregular. So idk if early implantation/ ovulation can happen. Well few days ago, had sex, he doesn’t finish in me but pulling out isn’t 100% but I had some red tinge discharge once when I wiped today . Now , the sex wasn’t rough or painful and no bleeding directly after . So I’m just curious 🤭🤔 what could be happening. I go to the OB in a week for other reasons but hmmmmm !?
