OPKS after Clomid.

Hey ladies I need some advice. I just finished my last pill of Clomid 50mg Saturday. Today marks 4 days. When days after the last pill did you get your positive opk. This is mine on day 4. I tested earlier at 230 and they were much lighter then they are now. Should I test again tonight or tomorrow at the same time at 230 or should I test earlier then that tomorrow?
