Should I go to the hospital?

B
I was told to go get checked out if I was having more than four Braxton hicks in an hour. I'm only 26 Weeks and I've had them pretty consistently since 3:45. It's now 6:15. 
I need advice on if I should go in. 
I'm asking because I start my new job in an hour and a half and I risk losing it if I don't go. I don't want to go to the hospital if it's not necessary. Please help.
