S.A.
I went through this with my 3rd pregnancy. It's miserable and there is nothing you can do about it. That's the hardest/most frustrating part.
I was lucky that I was able to lay down on my side A LOT! My mom was wonderful and took my older kids, and it was summer so they weren't in school. I don't know what I would have done without her.
All I can say is hang in there, stay hydrated. I was told that being hydrated was a major cause of early contractions. So drinks tons of water and try to lay down as much as you possibly can. This too shall pass!
