Pain in left side at 5w5d

I’ve been having on and off pain in my left side all day. I work at a job where I’m on my feet and I only sit twice in ten hours, unless I go to the bathroom. It’s not bad. Probably like a 1 or 2 on the pain scale. I went to the doctor last Wednesday for an ultrasound to see if I had an ectopic pregnancy, but since I was so early, I have to go back in two weeks. I get pains on my right side too, but not as much as my left side. The doctor said if the pain gets unbearable go to the ER, but it hasn’t. I’m just wondering if anyone else has pain like this? I’m also left handed and left side dominant if that means anything
