HELP ME MOMMYS.!!! **back pain relief**

What can I do to relieve my lower back pain.!! I’m 30 weeks and it’s just started the past week. It hurts when I stand up, when I move to try and get comfortable, when I stand for too long, or have been walking for a long time (like when I go grocery shopping for two hours) and then go to get into the car.!!!! I need relief. 😩😩
