Is it normal to ache so much?

hi I’m 5 weeks tomorrow and I ache sooo much!

This is my 3rd pregnancy but Iv had 2 miscarriages and each pregnancy has been soo different. This time my entire body aches like when you have the flu and my skin is sore. Particularly in my legs and upper arms. 

Is this normal? does anyone else have this??  I’m hoping this is a good sign.
