He came in me, pregnancy possibilities?

We use condoms as our contraception as I can’t take the pill and the coil wasn’t right for me. He’s 43 and I’m 41. Been together almost 5 yrs. Had an accidental chemical pregnancy 2 mths ago which I freaked out about as it wasn’t planned. Since then I made sure it was condoms in my fertile week 100%. Well 2 nights ago at 4am for some reason as we never have sex during the night, we had half asleep sex and he usually lets me know when he’s getting close and I all of a sudden In my sleepiness realised he hadn’t put a condom on and was about to say stop don’t cum in me and he started cumming. I burried my face in the pillow and started getting angry and he’s like what? And rolls off... I said you cum in me! Why did you do that! He said oh sorry I forgot you should have reminded me. The whole thing only lasted a cpl mins and we were both mostly asleep. couldn’t get to the shops the next day for morning after for other reasons.

I was according to glow 3 days before ovulation. What are the chances I’m pregnant? Especially at age 41 and it being 3 days before? I lost a boy at 25 wks and a boy last dec at 17 wks so I don’t want to do it again. It’s too terrifying and I have 4 kids that’s enough. Please no negative comments I’m really quite worried and I’m still angry with him for it and the atmosphere is heavy in here... 😨😕
