Can birth control pills help hormomes in mid 40's?

Sure, this is entirely possible!

Birth Control can help regulate hormones in Women at any age, but may become increasingly useless after menopause, as the Woman does not menstruate.

You should definitely see your Doctor for more information. Birth Control is simple and usually very effective at controlling hormones and menstruation.

It's possible that not all birth control types will work for you specifically, but ask your Doctor- there's bound to be one out there that can help.
