If I were you do all you are doing MINUS the herbs is the best idea.
You too young to mess around with any herbs.
I'd just add a collagen cream to boobs assuming its chemical free but msm should take care of that. Maybe add vitamin c alongside the msm to aid breast growth.
Give that at least eight weeks. Don't think about popping pills until you consult a natural health professional alongside providing them your hormone results and let them make the call to start herbs or not.
I understand the following applies.
Maca is an adaptogen and should balance you out. Hormones adrenals thyroid (possibly)
Fenugreek might raise hormone sensitivity. FYI my naturopath''s" thinks fenugreek has no hormonal influence but modern day research suggests it's estrogenic and linked to breast cancer..
Saw palmetto (Anti estrogenic) and you said you have low estrogenic already.
Vitex should raise progesterone and balance you out but higher dosages can make your boobs smaller.
See, I think the herbs you want to take contradict what you are trying to achieve. You really shouldn't fly blind taking herbs cause they can MESS you up. Trust me.
Just follow the rest of your plan 'for now anyway"
Good luck.
