Pregnancy scare. Doctor, i need advice?

Hello Doctor, I need advice regarding a possible pregnancy risk after having sex with my girlfriend. We had sex on 19 October and used a condom. During intercourse, I was about to ejaculate and decided to ejaculate while still inside her, assuming the condom was properly on. After ejaculation, when I pulled my penis out, I noticed that my penis had come out of the condom, while the condom itself was still inside her vagina. I then removed the condom manually. My concern is that I'm not sure exactly when the condom slipped off. There are two possibilities: The condom stayed on my penis throughout ejaculation and slipped off only when I pulled out, meaning the semen was contained inside the condom. The condom slipped off during intercourse without me noticing, and I may have continued penetration without it and ejaculated inside her vagina. I'm worried that semen may have entered her vagina, and I don't know how to assess the pregnancy risk. Could you please advise us on this
