Just keep doing long walks, bouncing on a birthing ball or even just the edge of your bed, bumpy car rides over speed bumps, nipple stimulation, you could even use a breast pump if you have one, orgasms cause contractions, sperm helps thin your cervix, crank up some music and
dance dance dance, galloping like a horse, skipping, jumping jacks, Just really staying up and active and using gravity to your advantage.
