Should I Be Worried?

I had unprotected sex two days before I ovulated and the morning after that. I'm POSITIVE I ovulated when I did. He pulled out but missed where he ejaculated and his sperm drizzled down into my vulva area. There was a lot. I took a Kleenex and wiped a lot of it off but shortly after that we did more foreplay down there that I think could have made the situation worse. Should I be extra on the look out for the flow this month?
