If she was pregnant and she knew it, I feel like there'd be some hesitation for her to do these aerial things, considering possible injuries and stuff pressing up against her belly. Heck, even camming naked, because she doesn't strike me as one of those content creators who wants to make money from pregnant belly content. Regarding the social event in OCT... did she go last year? Did she already say why she isn't going, even just an excuse?
I don't know, man. A few day ago, this almost had me, but the more I think about her busy scheduling, her family stuff, studies, exercise, cam events, it all adds up to her not being in any way ready for responsibilities like this. Like, by December, she'd be at a point where everyone would notice a more prominent belly and she'd have to go "Takin' a break guys, I'm preggers, so I'm gonna be offline for the next couple of months". That's a long time not making content.
Her family relies on her income, she said so herself. Her work helps them. I'll tell you what, if she starts ducking out of attending more stuff other than the October social thing you mentioned, like a few other in-person events at least, then I'm gonna believe it.
