Left side abdomen pain

Im currently 14 weeks, is it normal that every now & then i get pelvic pain on & off? (Still bearable) And also stomach somehow feels heavy/uncomfortable. And its always on the lower left side. Either around hips, waist or just the lower left side abdomen. Rarely on the right side pain. Although i only have very small baby bump. Is there such thing as baby gravitate more to left than right? #firsttimemom #advicepls
