Natural pregnancy with PCOS?

Kala • TTC #1
I recently started letrozole and ovidrel after ttc #1 for 19 months. They are requiring I have 2 ultrasounds a month to "monitor " my cycles. First cycle didn't work, so I started the pills over again yesterday. Not only are the extra ultrasounds and appts stressful,(yesterday I got to be sandwiched in between happy pregnant ladies galore in the lobby) but I just got my bill for my first month and it was 1,700$. Now add money stress to the extreme emotional toll of infertility. Have any of you ladies gotten successfully pregnant with PCOS naturally? I eat well and exercise, but am considering more alternative methods, because we cannot continue to pay that much. I am feeling desperate, so any suggestions would be great.
