First, a quick check
If any of this matches what you're experiencing, call your midwife or doctor before waiting it out. Checking is routine, and that's what they're there for.

If none of these apply, here's what's usually going on.
Most common in the 2nd & 3rd trimester. See what else is expected at your stage.
What's usually normal
Aching lower back, worse with activity.
Why it happens
