Gonal f

TTC after a miscarriage in August. We got pregnant with our first medicated IUI but unfortunately miscarried. Did another medicated IUI last month and it failed. This month tried timed intercourse since we were traveling but we are dealing with male factor. IVF is really expensive so I want to try at least 1-2 more IUIs. My RE said I could try clomid (used femara for the other ones) to produce more mature follicles as I only have one large one usually. OR I could try injectibles/ gonal f. I'm scared to do the injectibles because of the increase chance of multiples (fine with twins but not more than that) but I also think it could help me produce more follicles and help my chances since the male factor is clearly hindering us. Anyone try gonal f and have feedback?
