Follicle size

I only have one measurable follicle 12mm on cycle day 12. This is my last <a href="https://glowing.com/glow-fertility-program">iui</a> cycle before <a href="https://glowing.com/glow-fertility-program">ivf</a>. Is there still hope this month or should I be further along? I am on daily injections of gonal f since day 3. Any advise or success stories would be appreciated! I'm losing hope😢
