Clearblue Advanced OPK

Kara

I’ve been TTC for 3 months. Decided to use the clearblue advanced opk this month and I’m slightly confused. Today is my 5th day showing high fertility (the blinking smiley). I started running low on sticks so I bought another box and decided to check for a second time today with the new box. Showed low fertility now. Has this ever happened to anyone else? I don’t know why I haven’t gotten a peak day (non-blinking smiley) yet. Getting frustrated. :(
