Ovulation Testing

Julianna

Hi! My husband and I have been TTC for 6 months, currently on month 7. I’ve been using the Clearblue ovulation tests with the cheaper ones to track my cycle (I’ve been on BC for 12 years). Yesterday morning, I received a blank O. This morning, I finally got my Smiley Face. However, I just took another now (12 hours later) and it’s a blank circle again. Is it possible that my ovulation was that short??
