I am 56yrs old - postmenopausal- My doc just prescribed me Prempro for hot flashes and mood swings. I took this for one month and when I stopped my bleeding started. Its been 2 weeks and it won't stop. My doc says that it will happen if I stop taking the medicine and wants me to keep taking Prempro for 3 more years. I don't want to take medicine for 3 years. I can deal with hot flashes. My question is now that I am not taking Prempro when will this bleeding stop?
