Possible premenopause, or perimenopause symptoms are irregularity of the menstrual cycle, says Mayo Clinic. The time between periods becomes shorter or longer, and the flow becomes heavier or lighter. Other symptoms of perimenopause are hot flashes and disturbed sleep.
Hot flashes can disturb a woman's sleep, but it is possible to have sleep problems even without them, according to Mayo Clinic. Other symptoms are mood swings that range from increased irritability to depression. These mood swings can be caused by the discomfort of hot flashes, sleeplessness or hormones.

Fertility decreases during this time, says Mayo Clinic. However, as long as a woman is having a period she can become pregnant. If she wants to avoid pregnancy, she should continue to use contraception until a year has past since her last period.

Vaginal dryness can make sex uncomfortable, and low estrogen levels puts a woman at greater risk for bone loss and infections of the urinary tract. Incontinence and changes in sexual functioning are also symptoms of perimenopause.
