Trying to get pregnant

So my significant other and I are going to try to get pregnant when he gets back from deployment. I stopped taking my birth control in January. I was told to start taking prenatal vitamins 2-3 months before we try. What are some other ways? Any advice helps!!

UPDATE: he cheated while he was deployed and then said that he couldn’t trust me because I cheated 🤦🏻‍♀️
