First baby

Castillo,
Hi everyone.i am mae,i  turned 24 last february. I got married when I was 23. My husband is currently working abroad. He went home a month before our wedding but went back abroad after 2 months. During those days that we were together, we tried to have a baby but unfortunately "we" were unable to get pregnant. He is planning to go home this december, I know it's too early but I would like to be advised on how to prepare for a sure pregnancy, and everything.I hope for your response. Thank you
