My doctor diagnosed me with PCOS last year so he put me on birth control to regulate my periods. He also said for me to do the low carb keto diet which I did,but have gained my weight back just a little.

This past Tuesday I went to see him again for a wellness check up and I told him I wanted another baby become first of the year January 2023. So he told me to start taking prenatal vitamins. He didn't say when to stop taking my birth control and what kind of prenatal vitamins to buy.

I have read on other topics that other women who had PCOS had taken supplements and other vitamins along with their prenatal vitamins and it helped them to get pregnant. Do I need to buy other vitamins or supplements?
