Lutal phase defect

Does anyone have any suggestions on how to naturally lengthen your cycle?

I have pcos and I’m 9 months postpartum… Before my daughter, my periods were all over the place. I would get maybe 3-4 a year… NOW I’m getting them every 21-24 days, literally a week after I’m ovulating. I’ve already been taking supplements for a month and a half and I’m seeing no improvements 🥺

Triple omega

Vitamin b12

Vitamin c

Progesterone cream (i know i have a low history with progesterone)

Prenatal

Inositol

Iron

Unfortunately I can’t switch doctors for a little while and my OB says things will work itself out… they never have 🥴👌🏻
