Super heavy and uncomfortable out of nowhere

So I hit 38 weeks today, and I've been uncomfortable basically since 30+ weeks (which is just part of pregnancy obviously, no complaints there) but all of the sudden today I feel like this kid gained 3 pounds overnight. I feel so stretched and so heavy and sore Its disgusting. I can barely move and it just seems like this came out of nowhere once I got out of bed this morning. Anyone else have it hit all of the sudden like this? Luckily I know I have my csection scheduled in 11 days so I can see the light at the end of the tunnel. One positive to come out of me losing my natural birth experience due to my breech baby.
