Trouble sleeping!!!

Jacqueline • Wife. Dog mom. Real mom. April '16 baby boy. Sept '17 baby girl.
Anyone else starting to have some pain when sleeping on one side and then going to turn over? The other night I noticed when I sleep on my right side and wake up to flip to the other, it's starting to hurt to flip! Like I'm pulling something on my right side! I wasn't sure if that means the baby is completely on that side and when I turn it makes me stretch things out, cause it to hurt. Last night it was worse. Might have to start sleeping with my pregnancy pillow!
