Encouraging baby to move....

Rachel
Im 29 weeks baby has had his head in my pelvis unil about a week ago, I could tell because I was no longer feeling his hiccups in the same place. My ob was concerned that I was 50%+ effaced and a finger tip dialated at 26 weeks as my sons head was pressing on my cervix, causing me to progress, this time I'm 75% effaced and about 1 cm but doc was relieved to find his head not in my pelvis. Today I've been a bit crampy on and off and my belly feels a bit heavy like it did when h was in my pelvis, I have a feeling he's moved back down. Is there anyway to encourage this little booger back out of my pelvis so he isn't pressing on my cervix?
