And so I've been using InsideTracker, one of our sponsors. You can use a doctor if you want. But that's true not just for estrogen and progesterone, but for testosterone. Men and women typically don't measure their levels. They should be. And there's a sex hormone binding globulin called SHBG, which is important for binding all these proteins in the blood, these hormones. And if you don't measure that one as well, you're flying blind with your dashboard.
