When should I take a test?

Earlier this month I had a FemVue sono HSG procedure to check if my tubes are open. They are and the doctor told me 3 months after the procedure, pregnancy chances are increasingly higher. We BD on days when I was ovulating and tracked everything. Now it's my first menstrual cycle since everything and today will be my 3rd day that it's late. When do yall suggest me taking a hpt? I don't want to get my hopes up. Maybe I'm just stressing my body out from thinking about it so much. Please help.
