First pregnancy! A little worried...

Briana

Hey all so I'm about 13 and a half weeks with my first baby. I'm a CNA and I notice when I get home after my 8 hour shift my lower back hurts really bad! If I lay down and rest for an hour or so it goes away but I'm worried that my history of bad back injuries (both caused by work and from childhood) are going to start effecting my ability to do my job at all. I plan on talking to my midwife about it on May 7th when I go in for my 16 week appointment. Does anyone have any other suggestions or maybe even stories similar to me?
