Can’t get comfortable!!

I’m only 21 weeks but I feel like I can’t get comfortable at all. Whether it’s sitting or laying down or standing, I’m always uncomfortable. I can’t sit up straight and I can’t lay in the right position, standing just makes me feel like I’m going to pass out most of the time. I can get comfortable in bed for about 10-15 minutes before I have to reposition. I know it’s only going to get worse as baby gets bigger. I don’t have a pregnancy pillow but I have a regular pillow (hugging pillow) on both sides which helps a little bit. What can I do besides just suffer through it??
