Weird observation

Alexa • Micah Tyler born 08/31/17 💙
So I'm currently 37+2, and the past few days I have noticed that the very lower part of my belly out of nowhere, has become saggy... I've been very big and my belly has been tight everywhere up until this. I'm guessing this just means my baby is lower than he's ever been? The area around my belly button is still very tight and I can feel his bottom but below my belly button it's just fat 😭 I know I'm gonna look awful post partum and I haven't cared one bit about weight gain and stretch marks until now. Is anyone else experiencing this? It's so random and weird to me.
