The average couple takes a year to get pregnancy. Part of that is almost certainly the stress of not immediately becoming pregnant and then wondering if you can get pregnant.
When we started trying and my wife didn’t get pregnant the first month, I could tell she was concerned so I calculated when she would be ovulating and we focused on that week. Bang, she was pregnant. When we decided to have a second child, I did the same thing from the get go and once again she was pregnant immediately.
So planning helped avoid the stress of worrying.
