Getting yourself stressed up is definitely not going to be helpful. I think the first thing you need to do is to put away all the society & peers' expectations that your wife needs to get pregnant right away after wedding.

I've seen a lot of people getting a baby when they least expect themselves to so you just gotta enjoy your married life for now.

Ouch... to be honest, both you & your spouse have a long way to go when it comes to fulfilling others' expectations. When your baby is out, expect a lot of people to give you their piece of mind & expecting you to follow their advices.

Get yourself destressed. You won't be able to help your spouse much unless you free yourself from these invisible chains.
