Falls

I fell in the bath tub this morning and I havent felt baby move. I've been having frequent urination and back and breast pain. I've also felt pressure on my pelvis and all. What are these signs of?

UPDATE:

12: 55 pm

In the hospital, everything looks good with baby I'm gettin IV fluids, hopefully I can get some decent rest.

UPDATE:

1:30

They are keeping me overnight cause I'm having regular contractions that i can't feel. They've given me a second dose of the muscle relaxant.
