Hey,
I think that your FS makes the judgement on your IF issues and just really how well he thinks that you will respond to the drugs. Starting low is the best way to go because it means that they can go up just as they have done with you. Starting high is potentially bad because of OHSS.
I had an IUI cycle before this and was on 50iu of puregon and only produced one follicle. 150iu produced 18!!!! Really it is just trial and error.
I am sure others will know more about this than me though.
Fingers crossed your BFP is on its way!!
