Poor anon. Should've said that research found miscarriages to be more common than previously believed and that this specific one likely wasn't the first and definitely not the last.
It's these little details that make all the difference...
Look on the bright side, now you and hubby can have your DNA tested and find out how incompatible you are and that you have about a 25% chance of producing a healthy offspring. Yay, knowledge!
Depending on the woman, this will either help, or shatter them.
The actual odds are around 50% self abort. Mostly within the first month. 10-20% happen between 1 and 3 months. Critically, almost none of the risk is down to the mother. It just happens.
I couldn't get the fear out of my wife's mind on this. All I could do was quantify it, and lay the groundwork that it wasn't her fault if the pregnancy failed.
When I had a colleague who had 3 heartbreaks, and she was expecting her 4th we treated her with proper kid gloves, no carrying, no stress. It felt like a team effort.
I hope she had a happy, healthy baby and that she and the baby are doing well. I'm not normally a fan of euphemisms, but calling a miscarriage a heartbreak is fitting.
