@Windmill, my experience yesterday sounds similar to yours. I had my first scan since stimming. Results were 3 larger follicles, 2 smaller and lots (don't know how many) smaller again. When I asked, nurse said 1x16mm, 1x13mm, 1x12mm, 1x10 and 1x9.
She spoke to me with an apologetic, pitying tone - even though I'm on mild IVF - and said that my chances of success were compromised by this response 
. If she had a different tone, I would have felt more positive, as it was, I felt deflated.
After a word with the doctor, the decision was made to double my gonalF dose for the remaining 3 days before next scan on Friday. They're hoping this might encourage the two smaller follies to catch up and mature enough to increase our chances. Nurse said the other smaller ones were too small to be useful.
I was alone for this scan. It was horrible, like I'd been given the booby prize or something.
I asked what the cost would be for the extra drug - just enough until the next scan. £180!!! What?! I asked whether I could have a prescription, so I could order it elsewhere. I was told I could find it cheaper elsewhere, but that I would never get it in time because I needed it for the next day... so there was really no choice unless I decided to continue without and so I commented that they had me over a barrel, then.
I was late getting back to work as it was, so put it on a nother credit card and left. Felt a bit ripped off. I even asked whether they would cancel the cycle for a poor response - assured no. Thank goodness.
Having thought about it since, I don't think 3 good ones (potentially 5) is that bad - I opted for mild IVF for gawd's sake! I appreciate the point that upping the dosage might improve my chances. But I didn't like the way it was put, or the way the drug was strongly pushed - it felt like there was no alternative. Starting to feel a bit cynical about the expenses we're incurring here.
