Am I being paranoid?

Sarah
About a week and half ago my boyfriend and I had sex. It was two days after my period. He used a condom and when he started to cum
He pulled out and pulled off the comdom and came on my stomach. I was wiping myself off after and I wiped off the cum and folded the rag over and dabbed my vagina off. He said said something to me about it then about that not being a good ide so I stopped and washed myself off like normal but now I'm worried about it. My appetite has increased and my stomach has been hurting for a couple days now, but I'm also ovulating. My breasts aren't tender or anything. I always fold the rag over and I remember doing it but what if I didn't? Is the chance of getting pregnant high by accidentally getting a couple drops of cum on my vagina? Do you think my increased appetite and stomach could be because I'm ovulating? Am I worrying over nothing and just being paranoid? No nasty comments please I just want someone else's opinion before I lose my mind with worry.
