Progesterone question

Hey y'all, I've been boycotting reddit and don't have access to the Menopause wiki, so I'm hoping one of you lovely people can help me. I am perimenopausal (VERY), and I've been using the estradiol patch for a while along with the Mirena to manage my symptoms. I'm currently using the .075 patch. My doctor also prescribed Progesterone to take as needed for sleep (100 mg). My question is this; do I need to take the Progesterone pill daily, or is it fine to use it as needed for sleep, considering I am already getting Progestin in the Mirena? Thanks for your help!
