ADVICE-Extreme back pain 6w3d

✨Rae✨ • Genesis 30:22-23 💙🌈 #RainbowBabyMason
So I need some advice. This morning I woke up everything was fine. I was getting ready for work, took a bath, etc. went downstairs to get dressed and BOOM shooting back pain from my lower back. It hurts to walk to fast, climb stairs, sit, squat etc. the only position that is comfortable is fetal. I'm a little worried as this has a NEVER happened before and I'm pregnant. I'm 6w3d today and I'm freakinf out. I haven't been established with my dr yet. Should I go to my primary dr or ER with OBGYN capabilities? I'm waiting for the nurse advice line to open but I need opinions!
