Question about changes

Hi, I’m a 21 year old trans woman who just hit 5 months on HRT. I haven’t noticed changes, but others that know I’m on HRT have remarked things that I can’t see myself. But also, they know I’m on HRT, so idk.

Like my chest is pretty much exactly the same, I’ve always had a small amount of man boob, but that’s it. But recently, I’ve been told by two different people that my boobs are really obvious now even over my sweater and one told me that my left one was bigger than my right. I think I might be too early to get any changes, but it’s weird that they said they noticed something. People that don’t know I’m on HRT haven’t said anything to me or thought that I looked any different, so idk. Anyway, if they do start getting obvious, I might need to get a bra.

Anyway, is this a thing? Is it possible for me to not be able to see them? Also, I have a super transphobic Trump supporting family, so if they saw that I had boobs, they’d definitely take my HRT and send me away, so this might be serious if they see it and I can’t.
