Things like screaming, swearing loudly, or accidentally going to the bathroom may seen embarrassing now. During labor though, avoiding awkwardness will be the farthest thing from your mind. Nothing you could do or say during labor will surprise the doctors and nurses. They have seen and heard it all!
So, check your self-consciousness at the door when you check into the hospital/birthing center. Feel free to do what feels natural as well as what makes you the most comfortable. If you’re normally a loud person, don’t try to hold back your grunts and groans.
