Early Labor? At 33 weeks!

I've been having contractions last night but when I woke up this morning I was feeling fine. Then my SO and I had sex. A few hours after that, I started having them again. I'm not sure if they're real or just Braxton. Last night when I was having them, the nurse told me they were real(even though they weren't that painful.) They feel like A LOT of pressure down there and like something is being pulled down in my belly. No blood or gushes of water. I have some tiny little leaks but I feel like they may be discharge? I also have been timing them I've had 10 in the past hour and they feel really in tense. My nurse says i should go to the ER if they get more painful but theres only one hospital where i am and they take FOREVER. Is there anyone out there that can relate? What should I do? If it is early labor can they stop the contractions? PLEASE HELP. Thank you!
