Hi Chelo!
I'm not an expert on NBE yet. But I too suspect that maybe I'm a bit estrogen dominant.. not sure if my estrogen is high, normal, or low but I definitely think I might have low progesterone in relation to estrogen (hence, the dominance). Anyway, if you can't get a saliva hormone test done right now to confirm it, just start out with a very simple regimen of saw palmetto and maca for a few months. Maca is supposed to help with estrogen dominance and since you've already grown a little, that's a good sign that the maca agrees with you. I tried maca but for some reason it seemed to only increase my estrogen-like symptoms.
But I'm taking saw palmetto and it has helped me quite a lot with excess androgens and clearing up my skin.
As for the fenugreek, EPO, and wild yam, I would probably stay away from those for right now if you suspect estrogen dominance because they can all be quite estrogenic in my personal experience. I've read that wild yam is a progesterone promoter, but it doesn't actually contain progesterone.. it does contain diosgenin, which I believe is a phytoestrogen if I'm not mistaken. If you decide to use a phytoestrogen in your program anyway, maybe it would be a good idea to take something mild like fennel or a small amount of fenugreek just during your follicular phase which would coincide with your natural cycle.
There seems to be conflicting info online about the estrogenic properties (or lack thereof) in EPO but if you do decide to switch from it, I think coconut oil, cocoa butter, olive oil, or macadamia oil are great alternatives.
If any of my tips are off-base, I'm sure some of the more educated ladies on here will correct them.
But I hope some of this helps you. Wish you much success on your NBE journey!!
