Question 1

Can a single blood test confirm perimenopause?

Accepted Answer

No. Hormone levels fluctuate significantly during perimenopause. A single normal result does not rule out hormonal changes. Trends over multiple tests are far more informative.

Question 2

What cycle day should I test hormones?

Accepted Answer

Day 2–5 of your menstrual cycle provides the most reliable baseline for estradiol, FSH, and LH. Progesterone should be tested on day 19–22 to confirm ovulation.

Question 3

My doctor says my labs are normal but I feel terrible. What should I do?

Accepted Answer

Standard lab reference ranges are very wide. Many women experience symptoms when values are technically "normal" but suboptimal. Ask for specific values and track trends over time. Tools like PeriTrack use perimenopause-specific optimal ranges to highlight where your values could improve.
