Is this pain normal?

I'm 16+1 with baby on the left side. Throughout the day I've had numbing and pain in my left leg, but in the last hour I got this really heavy pulling feeling on the left side of my pelvis area. It's like heavy and sitting and radiating down my leg. I haven't had any bleeding that I've noticed, but I dont really look anymore. As far as I know I dont have any risk factors (1 unexplained miscarriage but very early on) and I'm not overweight. I'm not even really showing so I dont think it's from too much weight in one area. Has anyone else experienced this?
