Condom leakage ?

[Theunknown123]

Im a bit worried about getting my gf pregnant tbh, im a 20yo and she’s 36 we had sex 2 weeks before her period it was only once, as a guy i produce a lot of precum even inside the condom anyway sometimes i cum without feeling it like feeling an orgasm without cum or sometimes both and i would still continue without knowing and it will stay hard, basically i dont know if i came in the condom and continued but let’s say i did and I continued to have sex with her and when i was feeling it i pulled out and came outside its like using pullout method with condom im a bit worried if actually came and didnt know and that the sperm leaked out the base even tho it was a bit tight condom will there be any chances if she does get pregnant ?

She does smoke if your answer will include her fertility at this age
