Hello everyone again, who has a baby in their belly that's been actively moving? Don't know why? My mucous membrane plug came out a week ago, don't know when the birth will start for the firstborn? Pain in the back of the waist sometimes lasts long, recently went for an ultrasound to find out everything is okay, they said the water is slightly dirty and so on, but everything is good with each day it gets heavier but nobody cares ?? I get tired every day, I want to take a break from my soul but also because the mother-in-law does housework, I can't just watch and lie down and because of this I have to carry the day helping and lying somewhere 9-
