Fertility

I'm AFAB. This year I met someone amazing who happens to also be capable of having biological children with me, which is something I never expected to happen as I never thought I would be attracted to anyone who is not an AFAB woman, and I have also had a deep rooted phobia of pregnancy and birth up until our relationship. We both agreed we'd like kids someday if we get to that point and would adopt and/or have biological kids, likely both if we're able.

But I think this is bothering me a lot more than I ever thought it would. I've been on hormones for a year and she has been on hormones for half a year. I worry that our fertility is compromised and dwindling continuously and that we'll get to a point of no turning back. I never wanted biological children before now because they would never be mine and my partner's, just one or the other, but now that I have that option I'm afraid of losing it. The thing is, although I don't at all foresee us breaking up, it's obviously still way too early to jump the gun and make babies, only having been together for so long and hardly making enough money to get ourselves by. So I'm wondering how much time I might have before it's too late to seriously consider it.

Do any parents or attempted parents have any experience with this? I feel kind of selfish for even worrying about this because it wasn't so long ago where I couldn't even conceputalize why people bothered having kids instead of just adopting. And I'm also concerned that I'd have to take away my partner's autonomy in some way just to preserve fertility. I also worry that even if it's viable in the future, I'm underestimating my dysphoria and could put myself through 9 months of trauma.
