So...

Me and my boyfriend got caught up in the heat of the moment and decided to have a quickie the other night in his truck. He didn't have a condom but we still decided to carry through. He was very careful of pulling out, and even had to jerk off a while before he came, he wiped everything off of my stomach and even down there (just in case anything reached there). I didn't realize it was the day I ovulated, and I am so concerned about the pre-ejaculate. When doing anything else, he pre cums pretty heavily, but it's usually in a couple of clear drops. Should I be worried?? My period comes in nine days and I'm honestly so stressed out. I know he pulled out in advance I just hope nothing before that was enough to shake things up.
