Swelling in lower half affecting sleep

knottief8533854ec45f125

This is my second pregnancy, and I'm finding that at night I wake up feeling like my whole pelvic region (especially lady parts) is swollen. It's causing me to have a difficult time getting back to sleep. I've read that it's common to have swelling down there during pregnancy, but I was just wondering if anyone else has had it affect your sleep and if you've found things that have helped. Thanks!
