Hello girls. About a week ago I started to discharge some mucus, like egg white, it was not much and after that came out even today just a little bit. Today my back hurts and my belly feels tight, I feel the baby very low in the tummy area near the belly button, but there's no contractions or water breaking. I have an appointment only next week. Do you think this is already labor or just preparation?
