On the belly fat thing:
It takes TIME. Lots of time.
I've read studies that say that your body loses and replaces only about 10% of its fat cells in any given year. Hormones do not and can not influence how fat cells inflate and deflate as you gain/lose weight, because that always happens evenly across the whole body. Hormones can only influence where new fat cells are reborn after old ones die.
So basically, there's nothing you can do but wait in regards to getting fat on your boobs/hips. Right now, at 19 months, less than 20% of your body's fat cells have been redistributed to their permanent estrogen-influenced location, probably less because you're a bit older, so the body's cells aren't dividing as rapidly. (Which is why cis-women get curves a bit faster, because at puberty your body's cells are still in a constant state of division, where once you're older you're not growing anymore, so it's slower.)
And it it's any consolation, I too tried to gain a bit of weight because I thought it would go to my hips and boobs. It didn't. It went to my stomach. So, again, at these earlier stages of transition, that's just the way it is. Most of my trans friends have told me that they're still seeing changes even 4-5 years into hormones.
And, well, some of us just don't get boobs at all. I have a friend Arianna who didn't. She still only has a AA cup despite being 7 years into transition, 4 years post-SRS, and having gained 50+ lbs since starting hormones. Some girls just aren't genetically predisposed to grow breasts. And some cis-girls don't either. So it's not necessarily the fault of being trans. There's a reason why breast augmentation is the most common cosmetic procedure in this country, with 290,000 of them performed every year.
