39+1 and having contractions
So I've been having contractions that are 8-9 min apart for 4 hours and I'm 39 +1 today. At my last doc appt on Friday I was 2cm and 75% effaced. The nurse said to come in when I'm contracting 5-6 min apart. But worried that I will go to hospital when I'm way too dialated since I need the meds for step b. When do you think I should go into hospital?
