29 week baby kicks

So my baby usually kicks around 8:30-9:30 in the morning. I went out last night with family to dinner so I slept in, I felt some kicks when I woke up this morning at 8:30 but then they stopped. It's been 2 hours and I have felt a few light kicks here and there but not as much as usual. I'm thinking the baby could of been kicking when I was sleeping in. Has this happened to anyone?
