HI, I Am On Estradiol 1 Mg And Progesterone 100

HI, I am on Estradiol 1 mg and progesterone 100 mg daily for the past week, I was on Estratest for about a month and I was very agitated. In the past month I have gained 20 pounds and am miserable I can't fit in my clothes and my night sweats are gone, but I still don't sleep thru the night. Should I just stop taking the Estradiol and progesterone? My GYN said I should stay on them for at least 3 months to see what happens....I am afraid to get on the scale every morning and see another pound has crept on....
