In addition, when the ovaries stop producing estrogen, the fat cells and the adrenal glands take over. In addition, if we eat meat, we get added estrogen from the animal's fat or from synthetic estrogen the animal was fed to make it plump, plus there are many other sources of estrogen. So it's kind of strange that conventional medicine fixates on giving women estrogen when it's far easier to be out of balance with too much estrogen relative to progesterone. It is natural for the menstrual cycle to change when a woman goes through menopause. Unfortunately, as I said, most of us don't start off from a place of balance, so sometimes the menstrual flow can get very heavy or too frequent.
Natural progesterone is extremely safe.
I'd suggest you try it for three months to ensure you get balanced out but please, if you are bleeding excessively, consult with your physician. You can get natural progesterone orally, but you need a doctor's prescription. One reason for memory problems when you go through menopause is sleep disturbance. Too much estrogen which, remember, is common, is a stimulant to the brain, whereas natural progesterone can calm that down and allow you to catch up on sleep. Another reason for sleep disturbance is hot flashes, which natural progesterone also can help.
