Not me, but
1. one GF after 4 years fertility support, and IVF bub, then got UTD at 6months (the only time they DTD if she can be believed).
2. Another GF whose first IVF bub at 40years, had an oopsie at 45years, after trying IVF again multiple times in between.
3. Another couple who were on IVF for 7 years, had their DD via IVF, then got UTD naturally when she was 15mths
4. Another couple (mum group mum), second bub conceived naturally after first IVF bub, at 8mths.

Wish it would happen to me, but then I would feel guilty about the snowbubs...want to try with them first THEN get an oopsie!
