Tips to speed up early labor?

I’m almost certain I’m in early labor. I’m 39 weeks and I had my bloody show last night. I’ve been having very irregular contractions, most of which are only very mildly painful. I haven’t had any contractions since this morning though 😞. How can I get these contractions going or get my water to break? I’ve been walking around like crazy and doing hip circles on my yoga ball. Also had sex tonight. Contractions aren’t showing any signs of speeding up.
