Accidentally Impregnating Delivery Girl

I've been expecting a package to arrive from an online order. I had no idea that the delivery girl would be so hot! When she comes up to my door I greet her and strike up a conversation. She seemed to be into me and was noticeably impressed by my huge house. I offered to take her for a tour during which I convinced her to get naked in my bedroom. I let her know how much I want to fuck her. She seemed surprised and shy at first and was a little insecure because she hadn't cleaned up. But she lets me eat out her gorgeous pussy and finger her. Then she sucks my cock and lets me fuck her. She tells me that she wants me to cum inside her and in the heat of the moment I oblige. Then she tells me that she isn't on birth control and that she's ovulating. Did I just impregnate the delivery girl?
