I was definitely yelling during my second labor like an asshole.  The difference is my cervix dilated like a speed racer and I gave birth a few minutes later.  I don't think anyone was on the floor but if I ruined their day for 5 minutes, fuck em.  If you're in for a long day, then yeah shutup.  I got an epidural with my first because they loaded me up with pitocin and that shit was unbearable.
