How do I know if I am in perimenopause?

The most common early sign of perimenopause is a change in your menstrual cycle—periods may become irregular, closer together or farther apart, heavier or lighter, or you may skip periods altogether.[1][2][11] Other common symptoms include hot flashes, night sweats, sleep problems, mood changes, vaginal dryness, and lower sex drive.[1][3][12]

A practical way to tell is to look for patterns over time:

• If your cycle length is consistently different by 7 days or more, that can indicate early perimenopause.[2][9]
• If you go 60 days or more between periods, that suggests late perimenopause.[2][8][16]
• Symptoms like hot flashes or night sweats can happen even while your periods are still regular.[3][15]

You do not usually need a test to confirm perimenopause, because hormone levels fluctuate and tests may be unreliable.[6] If your symptoms are affecting your quality of life, or if you have very heavy bleeding, bleeding between periods, or longer periods, you should talk with a healthcare professional.[6]

If you want, I can also help you compare perimenopause vs. pregnancy vs. thyroid issues—those can overlap symptom-wise.
