Rib pain, anyone else?!

Samantha

This is my first pregnancy, I am older (34) and I have been experiencing upper ribcage discomfort bilaterally over the last 12 hours. No nausea or sharp shooting pain and no real trouble breathing, I can feel the tension at the end range of a deep breath of inhalation. Thought perhaps constipation pains but have had a few bowel movements now and still the dull ache is present. Roughly 7 weeks along now. Has anyone else experienced this discomfort?
