Early early labor

So I’ve been having all signs of early labor all week and I am trying my best to get this labor really started!! What can I do to get these contractions to get clsoer together and stronger? Today they’ve been about 20/30 mins apart ALL DAY and painful but not enough I can’t talk through them. Lots and lots of pressure, very painful period cramps, pooping a ton and nausea, lost mucus plug, lower back pain, dilated 3cm & effaced 75%.

What can I do to get this going? Been bouncing on a yoga ball any chance I get. And will try sex again. Full term.
