Did hormone imbalance cause my miscarriage?

i was 6 1/2 wks when i lost the baby. also have mood swings all the time for years, its hard to get pregnant, i dont have boobs at all really, i have heavy and painful mentrual cycles and feel ovulation. I have severe pms symptoms low blood pressure and sugar intake problems. they said i was hypoglycemic? is it low or high progesterone or estrogen. how do they fix it. can u try to conceive while fixing the problem?
