What is the normal Follicle size?

I went in yesterday cycle day 11 for a follicle check. I had two follicles size 10 which my doc said is very small. We are going to wait till cycle 17 for the ovidrel shot and then 36 hours later for the IUI procedure. Last months cycle was 32 days long and I had a positive OPK on CD 17. I took the same dosage of clomid this month. Could that explain why my follicles are so small or are my chances of getting pregnant really not that good this cycle? Yesterday was a really tough day so I am hoping for a little hope that it could be a normal size if I didnt ovulate till CD17 last month.

It's possible that your follicles just grow slower, plus you have a longer cycle so I wouldn't worry too much. A mature follicle (one that is able to be fertilized) is 18-20. Anything too small or too big isn't good. But you have 6 or 7 days left until you would get the shot so that's a lot of time for it to grow. I don't see why you wouldn't have a mature follicle by that time.

24mm is excellent size, follicles around 17mm to 24mm should contain mature eggs.
