Birth control timing with narcolepsy

I am considering starting on minipills, as I am unable to use regular birth control pills. My family has sadly cursed me by getting extreme migraines from any form of birth control that involves estrogen. Therefore the minipills.

The thing is, minipills are from what I know, very time sensitive and needs to be taken at the same time every day.

This is where narcolepsy comes into play. I do not have an official diagnosis yet, but I am currently waiting on a sleep study. But my sleep schedule consist of 15+ hours of sleep daily. This is usually by 7 hour naps and 8 hours of night sleep. But my nap times are very inconsistent and I can't figure out how to time birth control pills if I go on them. I don't think I can name a time of day where I consistently is awake. How do I go about this?

I have also considered just getting a copper IUD, but would rather not go through the pain of getting it. Also considering that I have never been on any types of birth control, I thought it would be a big jump for me.

TLDR: how to time minipills when your sleep and napping schedule are very inconsistent.
