Iui advice please!!

I was just recently diagnosed with unexplained infertility, my husband has low motility(33.6) and my AMH is 1.76( which is low for a 30 year old)

My doctor believes that i am a good candidate for IUI.

She gave my 3 options for IUI

-Pills(letrozole) plus IUI

-injections plus IUI

-combination of both plus IUI

All three range in different pricing of course

But is it normal to have all these options?? Or would it be ideal to go through IVF?

Thank you and sorry for the long post! 😊
