Those on Norethindrone - what is your dosage?

I started taking norethindrone .35mg about 4 months ago, but I've read that it can be given at higher doses for endo. Those of you that are on a higher dose - is it a once a day pill or do you take a smaller dosage multiple times a day?

Edit: I know people can take up to 5mg a day, but my question is - is it as one prog only pill? My OBGYN is claiming that doesn’t exist.

Edit edit: I was able to get an appointment with my good OBGYN on the 17th - I don’t have to go to this lady that doesn’t listen and keeps trying to push a study on my that I don’t want to participate in. Hoping to get much better reception from this doc and be able to explain some of the things I’ve learned in the comments today. Thanks!
