Pain on my left side

Since last night I have been having this SUPER sharp pain on my left side. I am 34 weeks pregnant. It feels like I’ve pulled a muscle but the pain will get super intense to the point where I can barely talk. Then it will get less. It isn’t low like cramps it is about half way down the left side of my stomach. I haven’t had any fluid leaking or noticed decrease fetal movement but this pain is getting old. It doesn’t get better if I sit or stand the only time it’s sort of better is if I lay down. My stomach doesn’t tighten when it happens it’s just extremely painful like I’ve pulled a muscle x5. Has anyone ever experienced this? Should I call my doctor?
