Could you still get pregnant at 52 even are menopausal already and having hot flashes?

The answer is: no

Menopause is the time in a woman's life when her menstrual periods stop permanently, and she can no longer get pregnant naturally. Hot flashes are a common symptom of menopause. The average age of menopause is 51 in the United States. After a woman has gone through menopause, she can no longer get pregnant, even if she still has hot flashes.
