Thank you everyone for your perspectives.
LacePrincess, I thought about that too... the huge investment in time and energy would make it all the more devastating. It can add up to years out of your life if it doesn't work first time.
I already know what an emotional rollercoaster it is to have miscarriages, waiting to try again, finally getting a BFP only to spend weeks terrified it wouldn't "stick" (And it didn't, 3 times in a row). It was torture. And worst of all I couldn't think of anything else during that time. I was miserable, worse than I'd ever been in my life. I'm worried it would be even WORSE after having invested $$$$$ into it too.
If only first time success rates were higher to justify the cost as well as the huge time investment, both physically and emotionally.
