Possible pregnancy scare

Jordan
So, I had sex with my boyfriend about a week/week and a half before I got my period last month. I am not on the pill currently. There was an issue with the condom when he pulled out (it was still inside me). When I went to the bathroom about an hour later, I wiped and couldn't tell if it was his semen or my discharge on the tissue. I'm like 75-85% sure it was his. I just woke up from a very realistic dream about being pregnant, and I've been thinking about this for a week or two now. Should I be worried about getting this upcoming period, or am I being paranoid? Please help.
