I don't know when to test!

Charmaine
I'm on day 29 of my cycle and I don't know when to test for pregnancy. I'm very irregular and most of the time I gotta take provera to even get a period. I've also been on clomid the past 4 months. I've been having some period symptoms but nothing yet. I don't know if I'm having s missed period cause I never know when I'm gonna get it. Is it still too soon to test?
