It could be that you're not making more T; you're just making more of the other androgens. Or possibly you're not making more T, but your estrogen is peaking at a lower level than usual. Or maybe a combination of both.
That's how I am. My T is in perfectly normal levels, but even though my estrogen dips and peaks the way it should in a menstrual cycle, it doesn't peak high enough to have much of an effect, and my other hormones are elevated. You actually can use willpower, over time, to affect your hormone levels, even if it's done subconsciously. For me, this resulted in a largely androgynous appearance (upper body wise). Perhaps I would have ended up looking pretty masculine with different genes, but the way I inherited genes I probably would have been at least a C cup breast size and with even curvier hips than I already have. Surprisingly enough, I only found that all out after going to a chiropractor and a gynecologist.
