My daughter has been bleeding for the past 3 weeks. A doctor has prescribed Norethristerone. She is 27, petite, a self-harmer,underweight, doesnt eat because she spends her money on other "habits". She has "lost the plot" on various occasions, enough that she has lost her 3 children to the ex partner. She is depressed more than 50% of the time. We cant be beside her 24/7 unfortunately... What will this drug do and what may the side effects consist of please?
