Perimenopause - HRT Questions

I am 49 and my doc has prescribed lowest dose estradiol (Minivelle) patch and NO progesterone for depression and insomnia. I do have my uterus but she said since I have my period every 26 days which sheds my lining, I don't need progesterone (which is prescribed so your uterus can shed). I was told by friends that I should be prescribed progesterone anyway and I am confused. Anyone know the answer?

For me hormones doesn’t work. I feel worst. Next week i have appointment with my ginec. and i will ask for a new treatment. It is a pellet they put you under skin and is same human hormones. To many people said to me is fantastic, but are expensive. 

my doctor told me the opposite.. if you are still having periods and go on HRT you have to have the HRT with both.. you only have the estrogen on its own when you have completed menopause. (12 months without period). From what i have read thats is standard practice with HRT.
