Irregular cycles and testing!!

Whitney

So I am on my first round of Clomid. Normally my cycles are ridiculously irregular. Like anywhere from 30 to 96 to 48 to 121 days RANDOM!!! So I got positive OPK test this month for the first time with the Clomid. My period is due tomorrow based on ovulation. QUESTION: With my cycles being irregular when should I take a test? Is it ok to test tomorrow because the Clomid made me ovulate? No sign of af yet.
