Increased fetal movement at 38 weeks

Kristen • Momma to 3 beautiful girls (2 of which are identical twins). Trying for final pregnancy (hopefully a boy!)
Anyone else's little one start going nuts this late in pregnancy? She went completely nuts for about an hour or so and I haven't felt that much movement in a while. Kinda worried me a little. Hope she's not in distress or wiggled herself out of position...
