Question!!!!!

So my husband and I have been together for 8 years and married for 1 year. We plan to try within next month. All these years being together we have never tried for babies but we have never ever used protection. No condoms, no birth control, just pull out method for YEARS. Is it uncommon that I haven’t gotten pregnant from not trying and just using the pull out method for YEARS??? I don’t want to overthink. Would it be my fertility being off? I do get regular periods and I’ve never missed a period and only taken one pregnancy test years ago because we had a scare lol.. so any of you girls can give input? But we will be 100% trying next month! I just find it interesting we’ve been having unprotected sex for many years with him and nothings happened. But like I said we haven’t been trying and he has not came in me once during our relationship. That’s why I’m just wondering. (Sorry for the long post!)
