What does "trying" really mean


So my husband and I have been having unprotected sex for 3 years and we haven't gotten pregnant.

I didn't want to be pregnant until the last 6 months. I usually follow and app so when it shows I'm fertile or ovulating I was avoiding sex on those days.

But now that I'm TTC I'm wondering what you need to do to consider yourself "trying"

are you supposed to check if your ovulating everyday? Or should I be doing something specific ?

Normally doctors tell you to try for a year and come back if you haven't gotten pregnant

I just don't exactly get it! Please someone let me know your opinion :)
