Lower back pain? Lose joints? Dizziness?

Su

Is anyone else dealing with irritating lower back pain? My back is so achy and I’m only 4 weeks.

Also, does anyone else feel like their joints are already feeling a little looser? I feel like my legs and back are all wiggly and I feel off balance. Am I just imagining this? I have been feeling a bit lightheaded so maybe that what’s really going on.
