impatient can I test?

Tara
I'm so excited and I don't want to wait but I'm on day 22 of my normal 28 day cycle. I took clomid for the first time this month. I have a progesterone test on Friday but I really want to do a pregnancy test. I heard about testing using an ovulation test but I don't know how that's supposed to work. I also have pregnancy tests but will that be likely to work this early? Advice please.
