Can perimenopause start in your thirties?
Yes. Perimenopause most often begins in the forties, but starting in the late thirties is well within normal, and a range of medical and surgical circumstances can bring it earlier still. Age makes something more or less likely. It does not make it impossible, and it is not a reason to stop investigating.
This comes up often enough that it deserves its own answer. Someone in their thirties describes months of broken sleep, a cycle that has changed character, and a mood that does not feel like theirs — and is told they are too young for this to be hormonal.
Sometimes that is right, and the cause turns out to be thyroid, iron, chronic stress physiology, or something else entirely. That is a fine outcome; it is an answer. What is not fine is closing the question on the basis of a birthday.
The useful response to "you are too young" is not to argue about the label. It is to measure properly and look at the pattern. Either the numbers support the story or they point somewhere more interesting.
