In my case, when I was on too little estrogen for ME, my face got very angular, I wouldn't gain weight no matter what I ate which in retrospect was GREAT, and my overall fat distribution was so so but guys apparently loved that, that skinny model look although it kind of made me look older too...Months after increasing estrogen to a dose that suited me better, I started gaining weight all over and having that more curvaceous, hour glass shape body with a fuller, younger looking face, slightly bigger boobs, etc. But, I also gained a little weight around my belly and now I have to watch what I eat

. Progesterone also seemed to helped me quite a bit, making me look fuller, rounder around the face, giving me fuller, more bouncy, prominent breasts.
My doctors focus more on if dose is giving me good results rather than levels which do vary in time and which really there is no perfect level as individuals vary in their sensitivity.
The best thing you can do right now, I think, is have a discussion with your doctor and see what they say. Share your concerns. Perhaps, too, the reason for your angular face could be stress...progesterone has personally really helped me with feeling less anxious in general...
Oh and also, if you are taking Spiro, that could explain it as it tends to dehydrate some and makes their faces look more sunken...
Just throwing out ideas...
