i have a body pillow that i use when DH is away, becoz i sleep with that on my left (which i throw a leg over) and a normal pillow behind.
When he is home however, i love to snuggle up to him, and him to me so i go without the pillows, i figure i can do this comfortably at the moment so may as well make the most of it while i can, coz i know the bigger i get i will def need my BP all the time.
I was never a belly sleeper but i couldnt now anyway, and i usually sleep on my back but i find i wake on one of my sides most times, but if i wake on my side without a pillow between my legs i usually have an aching leg or hips
