Help! ASAP!

Trinity • Mommy to Keanu, Azaleah, & Keenan

FTM and I’m 19 weeks and 4days. I have never felt like this ever! I’m having the most worst back pains ever! They’re even worst at night! I can’t even sit, lay down on my side, on my back, nothing! It’s really starting to hurt while walking too! I’m not quite sure what to do. The pain with 10 being the worst, it’s literally past that. It started in the middle of my 18th week but it only got worst then. My next appointment isn’t til March so I have so long... what should I do? Who should I call? Where should I go? What should I get? Just help a mama here.. literally been in pain for days now.
