If you did IUI before IVF I need your advice

Hi friends! I am in the unfortunate situation where we need to decide if we want to continue with IUI or move on to IVF

My husband and I had a successful FIRST IUI that ended in a miscarriage. We know we can get pregnant. We don’t know if we can stay pregnant.

We have done two more IUI’s and now need to decided if we do one more IUI or move on to IVF

If you’ve been in this situation or one that is similar, I would genuinely appreciate learning about how you made your decision.
