I don't buy she was ever actually pregnant with the baby herself. I think it was some sort of lab/surrogate thing, which she definitely has enough money to afford. You know, those celebrity pregnancies which seem to come at the perfect time for publicity, or like Beyonce who just so happens to have a set of twins that's a perfect 1 boy 1 girl. Except most who might be using some sort of fertility treatment or lab process are fit enough to carry the baby to term themselves. Tess is probably too fat to do that, but she's also too fat to even notice if she really has a baby bump or not. So she probably just acted pregnant the whole time (eating too much to emulate a baby bump, posting constantly on Instagram about "motherhood" for the attention) while some secret lady got paid to be actually pregnant with Tess' kid. Or they shot her full of a bunch of fertility treatments, but then she's fat enough there could still be complications while giving birth, so I doubt that's the case. A miscarriage or complication wouldn't be good for HAES, and I don't think they'd let happen.
