I get my OH to give me a belly massage and that seems to get things moving somewhat. I too am suffering terribly with constipation this time round on LT.
Oil up your hands (or preferably get somebody you trust to do it) then massage in circular movement CLOCKWISE from just above or below your belly button right down to the pubic mound. You'll need to be quite firm so that the intestinal tract is actually being massaged. Even better, massage using a dipping and rising motion. This motion will mimic the peristaltic motions that your colon makes when shifting matter through....the same sort of action that a snake uses to eat, undulating muscle wave like motions. I usually start at the top of my right pelvic/hip region and massage along, down the left hand side, across the pelvic region and back up to the starting point. Like I said, be firm as you won't hurt yourself and you'll soon be able to feel and hear things bubbling along.
If you get a sharp pain anywhere that means there is a pocket of trapped wind there, just grit your teeth and try and push it along, it'll be worth it in the end. Aim to massage for about 5 mins.
Good luck, I hope this helps.
