"FSH levels" are responsive to the need required for the ovaries remaining eggs to be activated for possible fertilization. At age "43" the occurrence of bleeding is not necessarily related to ovulation, but to breakdown of endometrial lining in the uterus, which happens when sustained estrogen is present in the absence of actual ovulation, so FSH levels can remain high regardless.
