Lower back pain at 9 weeks

Julia

I was walking around and suddenly felt an aching pain in my lower left back and it started to shoot down to my leg and into my knee. Almost feels like what growing pains used to feel like. My boyfriend was trying to massage the spot but it felt like it was on the inside of my body and he couldn’t quite reach it. Has anyone else had this kind of pain? There’s no cramping associated with it. My body just feels super achy.
