With regards to my (in)fertility, I'm unexplained and uninsured (no IF benefits).

It seems like using an FSA or HSA to pay for procedures,/meds would be a good option if I absolutely knew that I would need to undergo another round of IVF... However, I'm hoping that I won't...and by the time I know one way or the other (around the end of the year, after my FET), it will be too late to enroll.

Have you/would you consider using a flex spending account in this way? Any suggestions for my situation (in all likelihood I will in the next year A) be pregnant following FET, B) be doing another round of IVF with the associated costs, or C) any number of other contingencies (some of which, I suppose, might involve medical costs not covered by my insurance)? Any thoughts?
