How many IUI before IVF?

Filipa • Baby after FET, Unexplained infertility, IVF, 3 IUI

I am on my second cycle of natural ovulation - trigger shot - <a href="https://glowing.com/glow-fertility-program">iui</a>. I am wondering how many of these I should fo through before going to a more aggressive treatment. What do you think? If this does not work shall we go directly to <a href="https://glowing.com/glow-fertility-program">IVF</a> or try some injectable drugs for stimulation before? I have no ovulation problem.. . Please share some experience.
