When to start Premama? Help!

Sarah

Hi ladies! So I just picked up the premama drink mix. I was wondering when I should start? Currently cd 23 with no ovulation. Opks not even close to positive, creamy cm, and low bbt. I’m already on vitex to help with irregular cycles. Should I wait until CD 1? The problem is I never know when I ovulate or if I will 🤷🏻‍♀️ just wondering if I will screw things up even more if I start today. Any advice??
