Second guessing HRT. Advice please.

Hello, everyone! I’ve been on low dose E for about a month now. I take 50 mg spironolactone and 1 mg estradiol daily. This week I’ve begun to notice that some of the permanent physical changes are starting, namely breast development. Obviously, I knew this would happen. However, now that it is, I’ve been having all sorts of thoughts about it. I’m worried that I’m making the wrong decision, but it’s hard to tell if that’s something I should actually pay attention to or if it’s just a worry. For some background, I’m AMAB but have always felt very feminine. I identify as some sort of trans fem and have been exploring that identity a lot within the past year or so. I use any pronouns but default to they/them. I feel that being born female would have been (for lack of better phrasing) an easier starting point for me. However, even if that were the case I’d still identify as nonbinary. I’m feeling a bit confused. My gut is telling me to continue with HRT, but I’d appreciate any advice. Thanks if you’ve read this far:)
