Testing for thyroid is stupidly complicated. My primary hardly cks , just TsH. Despite having half of thyroid surgically removed. Only when I fussed did she send me to endo. He gave me a prescription, and just increased it, with testing in a couple weeks.

I felt better on the low dose, eyebrows grew up in a bit. And I feel even better on the slightly higher dose.

Get tested regularly. It's a serious issue with women, especially as we age.

It affects every cell in our body . It sets BMR.
