Lower back pain

Any one else experiencing it? I'm 12 weeks and 1 day today. I'm so paranoid at every little pain being a FTM. Ive got scoliosis and pinched nerves and had sciatic nerve pain even before my pregnancy. It seems my sciatic nerve pain has intensified 100% since becoming pregnant and causes my left thigh to feel like it's on fire. Anyone else experiencing anything of the sort this early? Thanks ladies 😭
