It might be that your new changes are due to the fact you are closer to menopause. Ask your doctor to check your testosterone and
estrogenHormone replacement therapy blood levels and your FSH blood test which is a way to see if you are closer to menopause.
You didn't mention why you had the D&C but a D&C only removes the lining tissue from the uterus. It often gets periods regular because it takes away irregular lining and lets the period start again fresh, but it is only a mechanical period and should not change the periods from regular to irregular. It might have just been coincidental in time.
After the blood tests come back, talk with your doctor. It might be time to consider adding estrogen which if low can cause both no periods and low libido. Replacement will help with those two things. Be sure and discuss the possible risks and benefits to see if estrogen is right for you.
