Perimenopause
The Transition Begins
What This Stage Means
Cycles become less predictable and many women start noticing changes in sleep, temperature, and mood. This stage can last for years.
Perimenopause is the stretch of time leading up to your final period. Hormone levels fluctuate rather than simply declining, which is why experiences can vary so much week to week.
Some women notice very little. Others notice a lot. Both are normal, and neither means you are doing anything wrong.
What You May Notice
- Periods that come earlier, later, heavier, or lighter than usual
- Hot flashes or night sweats starting for the first time
- Sleep that breaks up in the middle of the night
- A shorter fuse, more anxiety, or feeling unlike yourself
- Trouble finding words or staying focused
- Clothes fitting differently even with the same habits
