I too have gone through 1 cycle of injectables and IUI. I'm am taking Glucophage 1500mg everyday and clomid 100mg cd 3-7. On day 10 I'm to start taking the OPK and if there is a change in color prior to cd14, then I have to go in with DH http://www.healthboards.com/ubb/love2.gif
for 1 of 2 consecutives IUI. If no change in color by cd14, then my RE does and u/s and checks my follies. If they are of good size, then he would inject me there and a couple of hours later, do the IUI.
It is my understaning that once you get the HCG shot, then it meaningless to continue using the OPK. The HCG induces ovulation so you will ovulate a 1 to 2 days later.....
Hope this info helped, and lot's of luck this cycle guys!!!!
I'm on cd5 waiting anxiously for 2nd IUI. Do I have any cycle buddies!
