Should I go to the doc?

So I’m 33 weeks pregnant I have a cervical cerclage in but ever since last night my stomach has been hurting really bad on my right side it feels really tight. Almost like I have a charley horse in my stomach or something. I tried to sleep the pain off but it doesn’t feel any better it hurts to lay on my right side and walk. Having some back pain and cramping in lower pelvic area. I feel baby moving a little. I went to Burlington coat factory last night and was walking a little bit because I was shopping but do you guys think the walking made me feel like this?
