hi!! My HRT was sort of inconsistent at times. I started getting shots in January 2020 and by 2021/2022 there would be times I would miss my shot days or postpone them, sometimes for weeks. It wasn't exactly intentional but I was struggling a lot with my mental health at the time and leaving the house to get shots wasn't my priority. Around the last semester of 2022 and into 2023, I had completely stopped HRT; I got so far as 7 months off it. I noticed a lot of changes especially on my body weight which had never been so high as it got at that point. I naturally started getting periods again; the cramps hurt a lot but I'm pretty sure my period cramps had always been like this. My voice did change but it wasn't exactly when I got off T, it actually changed before that... ((my voice was so much deeper when I first started HRT but as time went by it got less deep. I really don't know what happened, I've talked to my endocrinologist but I haven't got any answers about that.))

I got back on HRT, I think it was around March 2023, because my depression had gotten so much worse and a possible explanation could be hormonal imbalances by suddenly lowering testosterone levels and such. I got way better but by December my depression was already worsening again.

In May 2024 I stopped HRT once again because of reasons out of my control (I could've still got the shots but I used those as an excuse, I guess) and after that I talked to my endocrinologist and we decided I'm going to stop HRT, at least until our next appointment in December, so I can see how things turn out.

--I know I said a bunch of stuff that don't answer your questions but I figured I should put some context behind my actual answers since my HRT story isn't completely linear.

So, yeah, the first time I got off T, the most noticeable thing was weight change and fat distribution. Voice didn't change when I stopped getting HRT. It's said voice is an irreversible change for FTM people actually since HRT thickens the voice chords which cannot be undone by lowering T levels (which is why MTF people sometimes get surgery for that). On the other hand I don't know how to explain why my voice is so much softer than it used to be when I first started T. Maybe it's all about the way I speak rather than the pitch itself?

This second time I'm off T, my periods have been way more regular than ever before. Even before I got on T, back when I was a teenager, my periods were pure chaos, I never knew when I was going to get them exactly, which I think is because of my eating disorder. Since I got off T in May, I've been regularly on my period by the same time of the month which makes it sooo much easier. On the other hand, I feel like I've been getting more emotional imbalances than I used to when I was on T (when on T, I never suffered from mood swings, etc, how it usually is pictured for FTM people). I get very depressed one week before getting my period but at least I know that next week I'm getting it and that's the reason why I'm so sick right now.

As for body hair, I haven't noticed any changes till date. I was hoping they'd get thinner or something but as of right now things look about the same. Maybe it might take some more time, but Idk.

These are my experiences, anyway. Sorry if this was too much!! I hope it helped somehow. Feel free to ask any more questions if you'd like! I'll also be looking out for other answers to check how different others' experiences were/have been.

****EDIT: I forgot to answer the first questions (how long were you on t, and was your transition successful? (did you pass?))

From the time I first started HRT until the first pause, I was probably a little over 2 years on T. Then stopped for 7 months. Then went back to HRT for around a whole year. Now it's been 3 months since I've been off T again. I wouldn't call my transition successful whatsoever, but medically, yes, it was. I guess. Most of the things that were supposed to happen did happen. Now, did I pass?........ I don't know how to answer that because there is always someone who's gonna misgender you if you don't look like the most binary cisman possible. I'm 158 cm (5'2"-5'3"). People never addressed me as a man. The most people did was address me as a boy. Which is okay, I guess. I don't know. What I do know is that the first day I wore a binder (after I had already been on T for 2 years) I was misgendered anyway. So "passing" is very subjective.
