Please tell me if someone had the same experience as me, i am 48 and was regular the last 15 years, then i had two periods in one months and started having mild hot flashes, no sleep and was late, i did blood work for estradiol, progesterone , testosterone , FSH and LH and it showed post menopause levels, how can this be so sudden?, i am in the US and cannot go to the doctor right now because of insurance, a friend Nurse put me on Vivielle- dot patch and prometrium pills and i feel slightly better as far as symptoms but that doesn't resolve any questions why it happened so suddenly.
