Condom okay?

So last week my boyfriend and I had sex. We used a condom but this condom had been kept in his glove box for several months. It was a quicky so after 5 minutes we both finished and he pulled out. The condom was wet on the outside(probably from me ?) but I wiped it and blew into it. I honestly made a balloon (weird I know) but it stayed inflated for a while and I looked and there weren’t any holes or anything so I assumed it worked. I have read that keeping condoms in the glove compartment makes the latex wear down so I’m worried about that. I might have been ovulating I’m not sure I don’t keep track cause I was on the pill but then i ran out of refills so it could take time for my cycle to regulate again. I took a plan b the same day but I’m worried semen seeped through the latex? I mean what are my chances of pregnancy?

I’m really concerned pls send advice

TIA xx
