My DH and originally said we wouldn't do more than 4 cycles - what we had saved would probably only cover that - but after 4 failed cycles, we both agreed to keep going, and we extended our mortgage to cover another 3 stim cycles, with the view of paying for any FETs from our joint account. By our successful cycle, all our money was gone, so we'd made the decision that if that cycle wasn't successful, we'd do a PGD cycle next, and if that didn't work, then we'd stop.

Whether or not we would ever return to it when money became less of an issue was something that we never discussed in detail, probably because we both believed we needed to find our own closure about stopping, without leaving the door open to 'what ifs'. I do know that we both knew we were coming close to the time we would have to call it a day, not just because of the money, but for our own sanity, too.
