Is it okay?

Dian • Married to the love of my life. Expecting our first baby March 2018❤️

I'm 5 weeks 4 days and my back is hurting a pretty good amount. This is my first pregnancy so I don't know if it's normal for my back to hurt so much. I'm not bleeding and everything seems fine except for my back.(lower back). I work full time in retail so I think that adds on to it. I just don't want anything to happen to the baby. It feels like if I have been bent over all day. Really stiff.
