Hurt my back-what to do?

Jessica • Twin momma (11 year old girls) and baby boy (4.5 months)

So in Indiana, we are getting pounded with rain. We hooked up an extra sump pump to keep the water levels down around our house. Needless to say, I slipped on our deck and landed on my ass/back. I am in a decent amount of pain, but I don’t think I broke anything, just sore from falling. I’m 9 weeks pregnant and I’m not big on taking meds unless I have to. Anything I can do to help relieve some of the pain?
