Boom, there was no reason for my recurrent MC's. I was 26, fit and healthy, perfect 28 day cycles, positive ovulation tests same day each month. I had multiple tests done by an RE and it was determined to just be "bad luck", which was very unhelpful to my sanity at the time.
It can happen to anyone, no matter their history. It recently happened to my good friend in her 20s, who already has a healthy baby. Three unexplained in a row.
It was bad enough to get BFNs after perfectly timed cycles at home after my MCs, but to get one after $20K+ as wells as 6 months of invasive testing, procedures, and emotional investment and obsession, I'm pretty sure it would destroy me. Then I'm pretty sure I'd want to try again, so it wasn't a total sunk cost, and then we'd be $40K+ down. And who really knows for sure if that time would work either? There seems to be too much working against it all to justify it for me, the way the technology stands now.
In all honesty, I wasn't very reassured after recently interviewing a highly renowned clinic by phone, and they're the ones who were supposed to be selling it to me. Plus the cost has risen inexplicably by several thousand even since the last time I spoke to them. How high would it be by the time we would have been ready to even start this whole thing? The whole thing seems wildly unpredictable and a huge gamble.
I'm sad because I thought it was the answer.
