So, when I spoke to my aunt years ago, I told her I felt like I might be male. She told me, "Well, honey, you've just been exposed to too many androgynes. I don't think you're male." While it's true that I have pretty severe PCOS, long undiagnosed and now just recently confirmed, I don't know that it can affect how I feel gender wise? Can it?

She's got the right idea just mixed up. Being transgender is caused by receiving diifferent hormones in the womb that don't match the sex or chromosomes we're later given. Once we're fully grown in the womb our brain has fully developed as either male, female or nb. You can't change how our brains are wired once we're born. Many trans woman were given T to get rid of feelings of being female with no effects but worsened dysphoria.

So yeah; maybe show your aunt articles showing the proper science of being trans.

What Elis said is accurate.

I had PCOS pre-T and didn't get it confirmed until I started HRT. I've met a lot of other trans guys who had PCOS pre-T, but not enough that I would say there's a significant correlation between the two. There are also plenty of cis-women with PCOS who have no issues with their gender.
