Second cycle

I feel like I'm all new to this since we got lucky with my first and used the flo app to track. Now that I am in my mid 30s, I would like to start trying properly. I have the flo app to track and I am using the clear blue digital ovulation sticks. I know I have only just started trying but is there anything else that might help? I think this time around, I am just more worried that it might not happen which doesn't help!
