Leg pain so early?

My previous pregnancy I had bad sciatic pain and leg/hip pain that started pretty early around 15 weeks and only got worse. So bad I went to therapy for it. I kid you not I’m only 6w5d and have the same shooting pain down my left leg but it makes no sense how it would even bother me this early! Anyone else experience it so soon? Maybe baby number 2 experienced it sooner for some reason?
