Ttc question!

Me and my fiance have been talking about beginning our TTC journey for baby number one very soon. I am very excited! I was wondering if you ladies had any tips on what changes to make, things to start before for a healthy pregnancy from day one! I want to be ready for baby to grow happy and healthy. Any tips? Any advice is welcome. Thank you ladies!

(Sorry if this doesn't go here. I figured this would be a good place. )
