Lower back pain

Hi all, I'm currently in Week 12, working from home and experiencing lower back pain(slightly above my bum) since last week - getting up from bed, adjusting myself to sleep towards my to left/right side, getting up from sitting on a sofa and even walking I'm feeling the pain / strain. I think it's pelvic pain. Has anyone experience in such an early stage? I have just bought pregnancy belt so I hope this will help me to get better in my daily life. #1stimemom #firstbaby #advicepls #pregnancy #lowerbackpain #backpain
