I am one of the ones who got headaches. Lower doses more spaced out fixed it. I have also been a lifelong headache sufferer. Your routine looks fine, although most literature and knowledgeable posts I have read suggest that progesterone is more appropriate after you have some growth, like at tanner stage 3, because it is part of the breast maturation process where they slow or stop growing and develop the mature shape for the boob and nipple. But this isn't an exact science so you may find you get great effect from it now. Congrats on getting some effects this early and happy growing!
