I'm about to reach 3 months on a combination of Spiro, Medroxyprogesterone and Estradiol (not sure if its valerate or the other one, all i know is that they are small blue-ish pills) and while I feel the changes have been minimal, people who see me either once a month or even every day (my wife) have noticed significant changes. Not a whole lot of physical which is fine because its still early, but emotionally, mentally and behaviorally, theres no denying that i'm female. My mannerisms, responses, reactions, posture, etc. All consciously and unconsciously female. My skin has DEFINITELY gotten smoother, it actually glows now and kinda glistens in the sunlight, and my body hair (while still pretty dark and fasts-growing) is thinner and shaving is not such a nightmare anymore. I think my cheeks are starting to develop and someone told me that my lips look fuller. And the more obvious changes are that my boobs have started growing, they are sore and tender and sensitive all the time, the areola has expanded and i have about a little bigger than quarter sized breast buds.... and this is only 2 months and 2 weeks in taking regular doses of everything.
My head hair is growing differently and my legs have reduced in size... I figured that a lot of all this can be related to how now I actually do maintenance on my hair and I'm on a strict balanced diet and hardcore cardio workout and muscle toning.... but the part of me that makes me believe the shrinking of my legs is hormone related to some degree is the fact that while my legs have drastically gotten smaller... my weight remains the same or 1 or 2 pounds lower... And you don't go from size 14 to size 10 simply by working out and dieting for only half a month (which is the amount of time i've been doing it all) so the hormones MUST be affecting my muscle mass to a very slow degree. All i know for sure is that i've never been this skinny in my life and i'm only BEGINNING to shrink.
Also; a lot of the times we cant see our own changes because we are too focused on what we've seen for years so sometimes we become fixated on those traits, but in reality there are many changes occurring. It also helps to do external, non-hormone related activity because, well, hey lol it can't hurt. All i drink is water and I only drink alcohol from time to time, and drinking water does wonders for your skin and for your metabolism. I also use face and body lotions and home-made hair masks. According to my mom, my face is becoming more feminine and my waist is developing

There are a lot of things you can do to feminize your body without the help of hormones (certain supplements for skin and hair, specific diets and exercise specialized for body feminizing), and a few miracle items like: COCONUT. Coconut water, coconut oil, etc. Its a miracle fruit lol You can also eat grapefruit sparingly to increase estrogen absorption but dont overdue it or you can cause harm to your body. I eat grapefruit (simply because I like it) maybe once every 2 weeks out of caution. Wish i could eat it more xD
ALL of this in just 2 and a half months seems highly unlikely, but it just proves that everyone is different. I still hate my body when I'm naked and I want my arms to shrink.
Side note: my eyelashes have also gotten longer, now I look like I'm always wearing light eye-liner lol, and if no one minds me getting slightly TMI, my "bits" have reduced in size dramatically. Probably the most exciting and surprising change so far has been my taste in food. I have a new-found liking for Black Olives, Plain Lettuce, Pickles, Blue Cheese and Blueberries after 23 years of HATING all of that and attempting to acquire the taste every year by constantly tasting it and giving it a chance... it wasnt until i started hormones that I actually began LIKING these food items lol... I havent found any food items that I no longer like though, which i find fascinating.
Take into account that this is all happening in a person who started off with higher than normal T-levels. The men in my family genetically produce more T than average (probably explains the genetic explosive anger lol)
I'm sure you've gotten some changes, but 3 months is still very early and the changes are still very subtle. Try to enjoy the mental and emotional changes because they are (in my opinion) quite breath-taking.
