IUI succes?

Hello beautiful mothers (to be),

I am currently in the proces of working with a clinic to become a SMBC. Since I am still relatively young (33) I expect that I have to start with IUI. I am not a huge fan because succes rates are not that great. So I would love to hear experiences from other woman:

- Did you have succes wit IUI, after how many attempts and which MOT straw?
- How many IUI’s did you have to do before the clinic was willing to move to IVF/ICSI?

I would love to hear experiences.
Thank you in advance!!
