Aches and pains

Linds
Hi all- I'm 6 weeks 1 day and the past couple days I have been extremely achy! I have a dull ache underneath my jaw in the gland in my throat on the left side as well as aches under my chest at the top of my ribs.  I don't know if I'm fighting a cold or this is another pregnancy symptom but it's no fun! Anyone else experience this?
