Early labor and Doctor said to wait at home :(

Lina
So I've been having contractions since 12:30 am that were 5 min apart lasting 1 min. Then I got some sleep from 3-5am but woke up with more intense cramping, back pain and contractions every 3-4 min. It's now 8 and I'm still feeling the city fractions so I called my doctor and he said since I was at 2 cm Friday I should wait until I can't breath through the contractions. I'm afraid then it'll be too late! The nurse I spoke to told me to go in right away but then he called and said to wait :( This is my second kid and am nervous about maybe dilating faster than he thinks I am.
