Hi Taurean, I'm a very slow typer so only saw your post after I had put mine up.
I'm pretty sure that a week is loads of time for the smaller ones to catch up. I had an U/S on Tuesday this week and had approx 18 follies most between 8 and 12 mm - 3 days later (today) I am told I have 30 and around 2 thirds are between 14 and 16 mm. Those little things grow like buggery so you have loads of time. Also as you say, all you need is one good one. I met a lady leaving the clinic today and she was absolutely beaming. She couldn't contain herself and said to me "I've got an egg!!! I know it doesn't sound so great but I'm 45 and this is my second cycle with nothing on the first. The follicle is 22mm" We chatted for a short while and I couldn't help thinking how happy I was for her but also how much luckier I am to be in a position where the odds are not so highly stacked against me - she told me that being over 45 they had given her very little hope but if attitude has any influence I think she'll definitely have a fighting chance. So here's to keeping positive; even when we feel completely crappy!

Bubbless - welcome to the group and go the righty!
