Help me ladies

Sooo I’m for sure i ovulate around the 13-14 this month ! I had my period from 1-6! I had unprotected sex the 17th he pulled out completely. I was even having pms symptoms already like my boobs were hurting and my cervical mucus was dry like before my period ! I’m 6 days away from my period spotting and have my ovarian cyst pain i usually get when I’m ovulating! I started spotting 7 days before my period though! What do you ladies think is this implantation bleeding ? I stared spotting four days after unprotected sex! I also took a test and it’s negative !
