I'm only 25 but i've been having symptoms of menopause, how is this even possible?

YES, IT IS: Unfortunately, some women become menopausal at a very young age. Having your fsh and estrogen levels checked, as well as having a pelvic ultrasound of your ovaries will tell. I know that the thought of being in menopause at your age must be very upsetting. The sooner you get an answer, the sooner your anxiety will be resolved. There are many options available to help your symptoms and to be preg.
