Go and see a doctor Cass. It really doesn't matter if you're going to have no. 2 in a year, five years or 10 years - you have questions and you deserve answers. The doctor will understand and you're NOT wasting their time.

I THINK my sister had something similar and was told that she'd never be able to have kids. So didn't use contraception and got pregnant at 35. She had another at about 37 BUT her DD was VERY premature. I don't know all the ins and outs and whether it was related to that so please don't read too much into it BUT I think knowledge is power so keep plugging away for answers from doctors - because unanswered questions will gnaw away at you.
