Condom got stuck inside me!

I had sex w/ my bf a few hours ago with a condom and he noticed mid-sex once he pulled out that the condom was halfway in me and halfway out. He didn’t ejaculate yet and was far from it and I’m also about 3 days away (projected) from AF. I would take a plan B but I already took one earlier this month and don’t wanna do too much to my body. But I’m lowkey paranoid.. what’re my chances of being pregnant? Any advice or input would be appreciated 🤍
