Ligament pain and achyness

Judith
So I'll be 17 weeks tomorrow and for like the last week the ligament on the right side of my stomach has been starting to hurt more often and its causing achyness in my whole lower abdomin. What can I do to help with the pain and achyness? Also is it normal to feel the pain from my pelvis (on my right side) to like the middle (right middle side) of your stomach? Sorry if that doesn't really make sense, it's hard to explain.
