I wonder if she has pregnant and has had something like a ruptured appendix while very early pregnancy? That would be a complex surgery and I’d assume there would be a lot of caution about things like post op bed rest to make sure all was ok afterwards. Conversely if she miscarried she would probably need time afterwards and might. It want to publicly announce it as the other kids are old enough to find out or hear it from friends? Also she previously had issues with the other pregnancies (hyperemisis graviardum) so maybe the prolonged period out of sight is to accommodate that if it should happen again without the need to announce anything too early ? Iirc they were kind of pushed to announce at least one pregnancy too early (when there was still risk of miscarriage) because she was hospitalized due to HG. Also would explain no info to the press as they have kids in school so may not want to publicize stuff that the kids would then get teased etc about? I think the whole shit show with the younger son is tacitly approved of by Charles for some reason as he’s still on the Royal website and the titles haven’t been pulled. Charles is paying lip service to William and his family but look at what he does not ehag he says. There are multiple negative stories about William and Catherine being fed to the press via Charles mouthpieces in much the same way he used the press to brief against Diana years ago. He doesn’t like being eclipsed in the publicity stakes and never has - he’s a covert narcissist.
