Progressing Labor

I recently went to L&D the other night for medical reasons and I was hooked up to a monitor. The nurse was telling me that I'm having contractions already but they aren't that close together. She checked my cervix and I was 2 cm dilated and 70% thinned out. Ever since that night, I've been having constant cramping/contractions but they haven't gotten closer in time and stronger. What are some things I can do to make labor happen faster since it's already begun?
