Test Question

My cycles are pretty irregular, so I'm trying to decide when to test! This cycle I started my first round of clomid and I think I ovulated on the 19th of September (didn't use opks). Today I'm 11dpo. Glow estimates AF to arrive on October 6 (17dpo), and another app estimates AF to arrive on October 9 (20dpo). That sounds crazy to me. When should I test? I don't know when AF should come, but I'll be 14dpo this Saturday, is that too early? Should I wait until next Saturday? I can't take the wait!
