How to regulate your period

Hi!

I have been having really irregular periods. We are going to try and start trying in December early January time frame.

I heard of a vitamin (I believe) that regulates your period. I remember it being about $50 USD for a 30 day supply. I read reviews and they were great! Anyone know of that or know of anything to help fix this mind if it’s on period of mine!?

I also ordered prenatal vitamins and folic acid to start my body prep. Other vitamins/advice you could give me?

Thanks 🙏🏽
