Iliana • FInally my Rainbow baby✨🌈
Hi, anyone here tried the clearblue digital advance opk.. I got 3days with the flashing smily is that normal? Im getting confused because my glow calendar says today is my peak day, but I tested in the morning and I only got a flashing smily face. Is my first cycle using the clearblue opk...
