Tips on TTC

Cait • 25. Married. Mama.
My husband and I are ready to start TTC, I just came off birth control in early December. We've been plenty busy this month but we will be apart for the next 3-5 months due to the military. During our time apart I really want to work on preparing my body to be healthy so I'm more likely to conceive when we try later this year. 
What are the best tips and tricks?
