Got irregular periods?
Do this: The surefire way to regulate your cycle is to start on very-low-dose birth control pills. Their 20 micrograms of estrogen (versus 30 to 50 in other types) offer pregnancy protection — and bonus hot-flash reduction.
Or this: Long bleeds result when hormones tell your uterus to start a period but not to stop it. "In some cases, your doctor can prescribe progesterone pills — either natural or synthetic — to provide the missing signal," says Andrew E. Good, MD, of the Mayo Clinic in Rochester, Minnesota.
