When to start HPTing?

Jordanne
Hi All, I have been TCC for 2 years, but this is my very first TWW! Tests and ultrasounds from 2 different OB/GYNs came back normal so they thought it was taking forever for the depo shot to get out of my system. Finally saw an RE and I have PCOS! So I did 50mg Clomid and O'd on 10/27. So because it's my first month of *really* trying, I thought I'd ask you lovely ladies how many DPO do you wait to test?
