Condom Came off

Hi guys…

So my boyfriend and I were having sex and in the middle i noticed something didn’t feel right. We realized that the condom had fell off and was stuck way up in me. We fished it out, and threw that condom away and got a new one. He didn’t finish in me, but I’m unsure if any precum would have gotten inside before we noticed that the condom had fallen off. My app says that my period is due in 11 days, and ovulation ended 2 days ago, but I’m still just a bit worried that I could get pregnant from this. Is this something that I should be concerned about or am I being totally paranoid? Thanks y’all!
