Lower back pain

I'm 17 weeks and one day, and I woke up a few hours ago and I can't sleep. My lower right back and lower right side like my hip is hurting pretty bad and I can't lay on my left side or right or back. I can't get comfy. I don't remember having pain this early in my first pregnancy.

I looked it up and I know j shouldn't have cause it said sciatic nerve pain and I don't feel like there would be any reason I would have that lol. Also I just sat up and im cramping a little bit in my lower abdomen and a little pain on both sides of my back, but most of the pain is in my hip/side, so I am just thinking round ligament pains now? Or tmi but poop/gas pains lol?

Just posting to see what yall think?
