Should small amounts of vitex be used with regular, combined bc that contains ethinylestradiol

Combined BC tends to be strong estrogen and weak progestin.  I’d not use PM and consider progesterone cream unless a hormone test says your progesterone is naturally high and estrogen naturally low.  Vitex can help a little but probably isn’t enough progesterone.  Up to 150-250 mg PC maybe, or whatever gives the most growth without side effects.  Less PC earlier on to confirm everything is ok.
