PCOS tips and diet recommendations?

Anyone conceived naturally with PCOS? Is there any tips or diets did you do?

I’ve been TTC since December 2018, I’ve had chemical pregnancy at January and in may went for check up and found out i have PCOS even though i have a regular period i took inositol then started 2 rounds of letrozole and 2 of clomid all with trigger shot, then took a break and started IVF and miscarried twice,

I’m thinking of doing HSG test this month but at the same time i want to go on a PCOS diet and tips I’m starting to gain weight for no reason even though my food is healthy and i workout so if there any tips or recommendations i would appreciate it
