I had sexual intercourse today (with protection, but the condom was taken off after he pulled out and began to masturbate) and he was cumming, but a little bit got on the top of my vagina. It wasn't far from the opening, but I wiped it off before it ran. Later, he had just wiped off a little bit of precum, waited 1-3 minutes, and then touched my vagina for a split second. I've been very nervous today, my last period was June 9-14, and today is July 3. I really do not want to become pregnant, how much of a risk am I at, and should I be worried?
