Help please!!

Have children is something my OH have always wanted, but with his work (RAF) we didn't know when. We have now decided this is the time. We chose now because if I get pregnant now. He won't miss the birth or first birthday. This is very important to us, to anyone really. So throw anything you have at me. Vitamins, brands of ovulation tests (UK) herbs, exercises, hell even positions. I know it's not as easy as that but anything will help. Many thanks. Xx 
Also new to the app. What is TTC?
