Read this short list. If any of it matches what you're experiencing, call your maternity team now — they would much rather hear from you and find nothing wrong.

If none of these apply, this is very often normal. 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
