1st cycle Clomid 50mg fail?

Marybeth
CD 22 and all I've gotten on the CB adv ovulation kit is flashing smileys. Today was my 6th day of flashing smileys. Is it safe to say the first cycle of Clomid didn't work? I'm on 50 mg. I've definitely felt my ovaries this month. Which is different. But no positive OPK. 😕
