Wondfo opk faulty?

Kelli • Married since 2005, and had our first child on June 16! We are so in love with our little boy!!!
Anyone ever have them be faulty?  I have had SO much ewcm the past 2 days, yet nothing that resembles a + opk.  CP is high and soft, ewcm is there, but the opk is not in agreement.  Grrr...
