So I've been having INTENSE back pain! I have been on my feet a lot today so I'm guessing that's what it is. My husband rubbed my back and I took a nap earlier then everything was fine. But then I had two meetings and ended up making two trips to the grocery store, then cooked dinner and now I can barely stand up straight! Ugh preggie problems!
