Congrats!!! We are also due on the same day!!! woohoo!!!

Ang- I also have pcos and was on clomid, but just lucky to hit the jackpot on the first cycle. I didnt test till 4 days after AF was due, but as u wud no with pcos AF can come at anytime.
My early symptoms were tiredness, higher temp and a little constipation. But i didnt really take much notice of these coz i have been TTC for 2 years.

I personally would hold out a little longer..at least till 3-4 days before AF is due coz i dont think u would be reading a high enuf hormone level to show on a test yet..

Good luck and i hope to hear some good news soon..
