Final answer:
Menstrual periods may become irregular and vary in severity as a woman approaches menopause. Menopause does not prevent pregnancy, but rather marks the end of natural fertility.
Step-by-step explanation:
During menopause, a woman's menstrual periods may become irregular and vary in severity. This is because the levels of estrogen and progesterone, two hormones involved in the menstrual cycle, change as a woman approaches menopause. As estrogen levels change, other symptoms such as hot flashes, night sweats, vaginal dryness, mood swings, and difficulty focusing can occur. It's important to note that menopause does not prevent pregnancy, but rather marks the end of natural fertility.
