I'm still holding out hope that I have or am about to O on 50mg Clomid, but just in case: when can I be pretty sure that Clomid is not going to work?

I took the pills CD5-CD9... I heard it can take something like 5-10 days for Clomid to make you O. Does this mean by like CD22 if I have seen no steady temp rise I should consider this dosage of Clomid to be a bust?

Just trying to figure out how soon I can call my doctor to get a higher dosage if it doesn't work.

Here are my charts for fun: http://www.fertilityfriend.com/home/pui
