Follicle Size and Ovulation

After my monitoring this morning, I found myself really curious about to correlation between follicle size and the LH surge to initiate ovulation. Based on conversation with my doctor(s), they consider a follicle 15mm or more to be mature, and will trigger (with hCG injection) once the follicle reaches 20mm. My question was "When does the body alone "trigger" ovulation?" Basically, I was concerned that by waiting until the follicle was 20mm, I could potentially ovulate on my own and miss it... especially considering the fact that we are doing our first IUI this cycle.  

So, I Googled, and found this link... I thought the information was useful, especially at putting my mind at ease a little during this "waiting period".  I thought I would share in case anyone was interested!  Enjoy!

  3. I just saw your post and thanks for the info.. I am 36 and have been trying since I was 18 to get preggers - no luck. Went in for first round of Clomid and ultrasound yesterday. They said my follicles were too small and I had no idea what they were talking about!
