is this normal??

so I'm 29 weeks and 2 days and ever since this morning when my baby starts moving it feels like he's twitching in there after he quits kicking and there constantly happening for 7 mins at a time it's only in spot on my right side and its light but then after a while he moves positions again and they stop for awhile then start back up is it normal for him to be doing this or does anyone know why it feels like he's twitching.
