The Saga Continues

Today was my cd13 follie check. The follies are measuring 26, 21, 18, 16, 14, 13.  I expected to get the hcg trigger shot, but they decided to push me another day in hopes that the size 18 and 16 follies will catch up.  They are very confident with the two larger follies, but having three or four in the running will increase our odds greatly.  I am a bit concerned with pushing this another day since I tend to ovulate on cd14 or cd15, however Dr. A is not concerned.  Should I ovulate before they give me the trigger tomorrow they will go ahead with an IUI tomorrow.  So, the plan is to trigger tomorrow and bada bing bada boom!
