Am I ovulating? Need help!

Hi everyone. I work as registered nurse in the ED or ER. I feel I am in my fertile window at the moment. I have a regular 32 day cycle. TTC no. 1  at the moment. Have been using the ovulating sticks but it's not showing up anything but have the clear discharge along with some slight cramping. Have been off the OCP for 4months now. Am I actually ovulating without it showing up on the ovulation sticks???
