Rey couldn't bring herself to tell anyone that Kylo Ren raped her while she was held hostage by the First Order. There was too much going on, it wasn't important, she would be fine, etc. And then she especially didn't want to say anything that would hurt Leia when she found out that he was her son.
As unfamiliar as she is with human biology, it takes a long time for Rey to realize that she's pregnant. And that Kylo has to be the father.
Cue frank discussions of what to do and everyone in the Resistance, Leia especially, being 100% accepting of whatever Rey chooses to do- whether she keeps the child, or doesn't, or gives it away for adoption. (OP is fine with Rey either keeping the child or not, so long as everyone else is there for her and supportive of her making her own decision.)
++ If Kylo finds out somehow and loses his shit. Kylo? Kylo is not supportive of Rey's choices. It's his child and nothing is going to stop him from taking it.
