Early labor extremely painful?

🌻🌼 • LoganVictoria 11/3/15 ☺️❤️
Did anyone have excruciating pain in early labor? I'm having extremely painfuo contractions 5 min apart since around noon yesterday, but L&d sent me home because I hadnt progressed at all from my appt that was on friday. They told me to take 975mg of Tylenol to help alleviate some pain but it didn't even touc it. And any time I sit down on the toilet, even right after a contraction ends, I feel like my back is going to snap in half.
