what can I expect with IVF?

My question is mostly about timing but any other advice/stories would be appreciated :) I have thing PCOS and my husband has low morphology. Our RE seemed to think <a href="https://glowing.com/glow-fertility-program">IUI</a> could work but after two rounds we are moving onto <a href="https://glowing.com/glow-fertility-program">IVF</a>. How long did your cycle take from day 3 work to transfer?
