38 weeks!!

So I have been having contractions since midnight and they were pretty intense so I got up and walked around went to the bathroom and when I wiped it was bloody so I called the on call nurse and she said that my contractions needed to be 5-7 minutes apart for an hour. Well I stayed up have more and more contractions and they were 3 to 4 minutes apart I haven't called the on call nurse since this morning and I am still having bloody discharge. What should I do this is my first pregnancy
