Girls, hello! I'm having my second birth, they say every birth is different, right now I can't understand but I have a feeling that I'll go into labor soon)) My lower back hurts and my belly feels like it's hurting sometimes, like period cramps. My first birth, water broke immediately, but here it's unclear and I'm anxious ? Do you think I'll give birth today or tomorrow?
