Contractions and doc wont listen

Cassandra
Ok so for the last two weeks ive felt a gush of fluid once in awhile and i also get contractions that are so painful i cry and alot of pressure in my vaginal area... every time i call my doc she says its just braxtons and to lay down. The other day i had 5 in 2 hours. She keeps telling me just to lay down. This is baby #3 for me and these do not feel how my braxton hicks did with my first two. I dont know what to do.
