Symptom Question

LJ • 1 baby girl with another baby on the way
Hey everyone I'm 5 weeks pregnant today,
​Still waiting on first doctors appointment.
​I'm having horrible lower back pain tho, it just feels achy and stiff or something. It's ok when I get into a good comfy position but then when I get up it's just so stiff and takes me a while
​Anybody else experience that??
