For me yes no visual result for 1 month at least. Puffiness more around 2 months for me. Of course everyone's experience is different with different estrogens, different medicine combinations, forms of estrogen, amounts of estrogen, and dna genetics.
I also saw only small changes till 3 months, at 4 much more.
This is just in my experience. I am sure TSes with higher doses and different stuff have much more quick changes.
The small pains I felt before 3 months was nothing till then. At that point the real pains set in, very aching and the actual tip seemed to double in length. But any touch against them was very sharp and they seemed to hit everything.
I am sure the others will tell of their own experience to, and Kathy getting 4 months experience with big results, sounds like more experience then me.
