@Hyolobrika @antisophon @VD15 estrogen in birth control is but estrogen for menopause HRT or fHRT is always animal in origin.
it bothers me that my birth control has lactose even though its just a minute quantity. i used to worry that the stearic acid in the magnesium stearate in them was animal in origin but its almost 100% certainly palm oil which is like, better only kind of.
stupid endocrine system hopefully i won't always need them
