On the "Meet the team" page on their website, there's one with the same first name who sort of fits the description I got - maybe she got married? Her name is very familiar, I think I might have met her before somewhere. Apparently she used to work at the Women's, so it's possible I had an appointment with her there with Amelia... And there was a midwife with the same first name who was with me when Ianto was born. It'd be amazing if it turns out all these things are true and I've unknowingly seen the same midwife through all my pregnancies!
