Help!!!

Okay so I had VERY VERY positive opk's about 5-6 days ago.  I mean test line way darker then the control. I got a peak reading on my clear blue as well.  I had tons of cm. side pain, etc.  CP was high, open, and soft.  This was on CD 20.  This is a bit early for me to ovulate (this was my first month on clomid, so it was expected.). Well I know you shouldn't but I have continued to take opk's because I felt like since my cycles have been so messed up I wanted to watch progression of the line.  Well today (cd 25) I took a test- the strip wasn't positive but my CB has a high reading.  Past 2-3 days it has been low?  Anyone have any idea what's going on? Odd?! Thanks!!
