Clear blue digital ovulation tests

Has anyone had problems with these? I have been testing faithfully. I had all the symptoms of ovulation and the test gave me the thank blank face 😞. However I stubbornly took a regular line one and it gave me what I thought was positive.... my new doctor gave me progesterone tablets to start after 2 positive tests this month. This is totally new to me. She recommended the clear blue. I called her today, confused on whether to start it, since I only had one, non recommended positive. Her nurse told me to try again next month 😣it's been 3 years of this! I don't want to wait! Has anyone had problems with the digital? I was trying to take the guess work out of it and that definitely didn't happen!
