Gonal F, iui, and follicles

I am just curious for those that have had an iui with gonal F, I am taking it cycle day 7 & 9. How many mature eggs did you produce and did you end up with multiples? I have cervical insufficiency so my Dr wants to avoid twins at all costs but we've done 4 iui's with famara, and no success. Our only other option is IVF and we just can't afford that. I don't want to have to cancel this cycle if I end up with more than 1 mature follicle so I'm just wondering how many women got more than 1 egg with it. Any answers help! Thanks!
