Lower back pain at 12 weeks? Help!

I have the worst lower back pain and it especially hurts at night I can never get comfy one being my back and one being I feel constantly sick..

Is it normal to have lower back pain so early? If anyone has the same any tips to relieve it..?

When I lay on my back it sometimes feels like it locks and it hurts so much I can’t move so I have to roll to the side to move positions.. I try and sleep on my side as much as possible as I know that’s what your meant to do but whatever side I lie on it seems to hurt that side of my back :(

I feel like an old lady! I would just love a back massage but I know I can’t.. any advice please.. I do not have a pregnancy pillow maybe that will help, any advice to the best ones I’m from the UK..
