Basal body thermometer

Li

Has anyone had success with getting pregnant using the BB thermometer? I never know when I’m ovulating (PCOS) and because of this I’m using a lot of ovulation strips. I ordered a thermometer off amazon with hopes of finally falling pregnant. We have been trying for a year and a couple months. I’m 26. And yes I have been had the blood tests and a ultrasound nothing out of the ordinary. TIA :)
