achy?

I'm 11 weeks, 2 days and the last couple of days, my belly and back have felt achy. Like when you're getting the flu/have the flu achy. I feel fine otherwise and it's only on my right side of my mid belly and in my lower to mid back. Is this normal? I tired looking it up and couldn't find anything about people feeling achy. I'm so close to being out of the first trimester and just praying everything is okay! Please let me know if you've had this or heard of anyone that has. Thank you!!
