Sam • my name is Samantha sam for short im 24.This is my first pregnancy. It`s been so easy for me. Having a little girl so excited. Cant get help starting to hate this app.
I'm currently 35/3 days and for the last two days I've been having diarrhea​ Idk why could that be any indication that baby might be coming? Has anyone had this symptom? I'm a new mommy don't know what to expect.
