I'm back on Clomid again after taking a few months off. 3 of my previous Clomid cycles I didnt get my +OPK till CD 15'ish. 1 cycle though I completely missed any +OPK & looking back pretty sure I o'ed at like cd8. Now that I'm back into charting/temping, the whole 9 yards I dont know when to start testing again, thinking CD 10 or 11 & hope for the best. I use the clearblue easy digital so its a nice clear + or - and no guessing. Let the fun begin !!!!!!!!!!!!!!!!!!!
