I feel ike I post so much on here. More than I should.

My tummy hard n it's been hard. It's really sensitive at the bottom. But I've also been slashed open by my ex. I've read where it's really only common to happen at the end of ur pregnancy however this is my 10th time being pregnant and I'm having triplets. So I feel like it's gonna be faster in a sense. All I know is I feel like I'm just fat n gaining weight. But my wife knows I am n all the signs and symptoms are there. But I've lost so many bf I'm so scared about this one. And ik some pregnancies are weird I'm also not sleeping good either as I don't have a house or bed. So yeah it's making things uncomfortable in many ways. But help ig can anyone ease my mind. Calm me down tell me this normal. Anything. I'm so scared
