Am I doing everything right?

We're TTC our first baby. I've got a doctor appointment scheduled for next week to go over everything with my doc. I'm working on eating better and getting more exercise. Making sure to track my CM, bbt, period, weight, sleep, sex, and OPKs, all kept in a journal as well as on this app. I'm taking a prenatal as well as fish oil daily with my breakfast. Even bought some Preseed. We just started trying and I want to make sure I'm doing everything right. Any suggestions?
