Hi Lucy & Nasrin,
Dr. C has me taking it primarily because usually when I take stims, I stim REALLY REALLY fast (like 5 to 9 days fast), which apparently isn't good for egg quality. And it did work for that purpose (regardless of the crappy things it also seems to have done.) I ovulated on day 14 last month for the first time in a long time - I have been ovulating anywhere from day 9 to day 12.
Do you two ovulate early? That may be another reason they gave it to you if so.
