Should I test, or wait???

Alexia
My cycle is very normal, on average a 29 day cycle. So this cycle I took a Clearblue ovulation test on CD8 and it said peak fertility, so of course I BD... I'm on CD22 and Glow is saying my period is to start TODAY, however no AF. Should I wait to test until CD29 or test today?? Need some advice, please!
