I would say no not normal.
Have you ever had severe menstrual pain before?
Adenomyosis could be why or Endometriosis. However there could be many reasons why this is happening but I would need more information.
I am also 43. I was having awful periods as well as baseball size clots at age 33. I went to my gyn, and we agreed to have an endometrial ablation done (google that). If you are done having children, this may be good for you. I still have a good sex drive, and I now only spot a very tiny amount for about 2 days once a month. Blessings - Blu
