You are talking about two drugs and two different results. Right now the Spiro is doing the heavy lifting reducing your dysphoria, reducing the hair and softening the skin. The estradiol will do the body shaping producing a more feminine looking body. It's very difficult to tell you how much your body will change. If you are skinny as a rail you might find it takes longer to see results. If you already have moobs, results may happen pretty fast. After 10 year off HRT I have returned to a different tablet and at a lower dosage than your's and I am seeing development beyond my past treatment so it's difficult to tell. Watch it for a few months and if things are happening to fast, ask your doctor about reducing the dosage.
