I thought it came out when she broke up with Kumar
Nope. she finds out she cant have kids in S7 ep. 12. 3 episodes after that Kevin breaks up with her, then Ted confesses his love for her, then they decide to move on from each other as Robin goes away for a couple episodes
Barney was pursuing Quinn at the time and him and Robin had little contact at all during those episodes (because he had moved on, this is even where Barney in full honesty tells Ted he doesnt care if he wants Robin, but oh wait no nevermind that scene apparently means nothing)
Everyone keeps assuming shes told people because it would only make sense. But no, she has yet to tell her fiance that her womb is bare 2 weeks before the wedding. Or anyone for that matter. They have completely ignored it.
