Tips on inducing labor

Went to l&d; last night for decreased movement. Turns out I was 1cm (I was closed on Wednesday) and having contractions every 2-3 minutes. They told me to walk to halls for 2 hours, and when I came back there was no change. So these contractions aren't doing anything to progress me. Give me tips of how to get these bad boys to be real. I tried sex, walking, and spicy food. I'm against castor oil.

TIA xoxo
