Menopause is the point in time when a woman's menstrual periods stop. Menopause happens because the ovaries stop producing the hormones estrogen and progesterone. Once you have gone through menopause, you can't get pregnant anymore.our doctor also could test the amount of hormones in your blood. But because hormones change during your menstrual cycle, these tests alone can't tell for sure that you have gone through menopause or are getting close to it. Unless there is a medical reason to test, doctors usually don't recommend it.
Blame it on the changing hormones of pregnancy. Watch out for mood swings during your first and third trimesters -- but be aware they can occur anytime.
