clearblue digital ovulation kit

Rianna
Hey ladies! We are ttc but haven't been having any luck. So I went out and bought a ovulation kit. I started taking it and got low first few days and then got high fertility.  I got excited because I thought it was working. Now it's been 8 days of high
 fertility. The website says to stop after 9 days and start again next cycle. Has anyone else have this happen before? Really disappointed. Been waiting for a peak fertility and now have to wait another cycle and these kits are expensive. 🙁
