Would you seek treatment if you had secondary infertility?

Despite having a mc I would say my hubs and I had little trouble conceiving our daughter as I was able to get pregnant on the first try twice and only took three months to get a sticky baby.

In order to get my first child I would have done any and all IF treatments necessary. But now that I have her, I don't think I would seek IF treatment if I had secondary infertility (maybe clomid but definitely nothing invasive). My husband however said he feels very strongly about having at least one more child and would do anything up to and including IVF. Hopefully this is not a decision we will ever have to make but I was surprised we felt so differently.

What would you want to do in this situation? What about your SO?
