Hi Mealsy,
Mine was a bit different but I guess everyones circumstances are a little bit different and I wasn't on Clomid. There were clear signs of my ovulation and that my body was producing enough FSH each month. But this is what I had to do:
Started puregon 50imu from day 5 and I had blood tests every second or third day from then on and blood tests every day close to my surge like you've got. But I had one ultrasound about day 11.
I'm guessing that if you're starting low dose of FSH day 9 there really isn't any chance of overstimulating as the ultrasound is to make sure you are not overstimulated and producing multiple eggs which is near impossible on a low dose of FSH for a couple of days.
Can you get your hubby to inject you? Mine does and it makes him feel a part of the process and the one time I had to do it myself I sweated over it for about 30mins :)
As I've said before IUI is no biggy, honesty! Relax be healthy and you'll be fine. Good luck.
