Help with OPK

Marissa • Mommy to Jaxson Finn 8/10/18 💙

Hey guys, I need some help! I’ve been testing daily since the end of my period and I’m currently on cycle day 13. Last month I got a positive result on cycle day 12. My lines have been all over the place and tonight it looks like a positive result (am I right? Stick on top) but when I double checked it with a clear blue I did not get a positive result. Why could this be?

Update: got 2 error messages on my clear blue test so I’m thinking there’s something wrong with it.
