Major back pain!!

Alyssa

I'm 19 weeks pregnant today and I woke up with the WORST pain ever. I sleep on my back mostly, but when I woke up it was so bad I couldn't go back to sleep and I nearly wanted to cry. January 2016 I had back surgery on my lumbar vertebrae so that could possibly be it now that my little girl is growing faster? But I also had weird pains/feelings in my stomach, even when I roll on my side it all hurts. Back everything. I won't be able to talk to my doctor until next week but does anyone have any advice? Or know what it could be? Thanks.
