Advice for hypothyroidism?

Hey y’all!

About 6 months ago, I was diagnosed with hypothyroidism and began taking medication for it. Prior to this, I would occasionally feel more tired than normal around my period, but nothing too serious. Recently, however, I’ve been feeling exhausted from the minute I wake up until I go back to bed, no matter how long I sleep.

Has anyone with hypothyroidism experienced this? I think it might be that my medication could be affecting my period and making it worse, or that my medicine isn’t as effective anymore.
