Hi Alex;
I was on a low dose of Progynova for about 2.5 years to keep the dysphoria at bay, but over time as the body adjust to the levels of Oestrogen unfortunately you will finfd you need to increase you intake/dosage (as per your docto's instructions otherwise you will slip back into dysphoria. After 3.25 years I have now found myself on a transition dose , because without I get quite depressed and down. Anyway unfortunately even low dosage means nipple growth. Mine were fully erect after just 2 months and when I am aroused my areolae and nipples grow in size. It comes with Oestrogen and Progesterone. . If rarely I have to present as male (not often thankfully these days!), I wear a vest and a baggy shirt and in winter a woolly jumper. It helps to hide the shape, but you probably need to wear a bra to stop your breasts from jiggling to much. Just don't wear a padded one. For me after 3.25 years on HRT, I am a large B Cup heading for a C cup. Al my female relatives were DD.
So it is to be expected. What I have noticed though is that after 3 years the breasts really start to round out and lose the traffic cone look.
