Clomid day 5, help!

Amanda
I was prescribed Clomid days 3-7 but my doctor told me to wait until cycle days 5-9 until she got my pregnancy test back. It came back negative and we got the ok to take it. Well when she originally prescribed it for 3-7 she told me to test ovulation starting on day 10. Should I start testing on cycle day 10 even though that was for 3-7? I've heard testing early can give you a false positive ovulation test if taken too soon after your last dose. I called today and left a message with the nurse but never got a call back. Today is my last dose so should I start testing tomorrow or wait?
