Yeah, I would suggest calling your dr to see if she wants you to go in for a checkup. It's always better to play it safe. Most of the aches and pains that come with pregnancy, I would describe as uncomfortable not unbearable so if you feel anything severe, get it checked with your dr ASAP. I really hope it's nothing serious. Good luck. :)
I would call her.. because then that way if it is something they can detect it right away..
