Girls, hello! Something spilled out of me this morning, straight onto the floor when I was getting ready for the shower. It's like mucus, but not water. It's also such a brown-yellow color. After that, pains started coming regularly. I talked to my doctor, he said come to the waiting room, we'll take a look. What do you think, is it time to have the baby? I'm just afraid they're going to send me home again (saying it's training).
