Ok so I'm 33 wks pregnant and my little darling has been doing this for a while now.

I may be over reacting but it's starting to bother me.

I'll be lying on the couch or in bed and all of a sudden she will kick up a fuss and shake like a crazy person!! maybe 6 little shakes in a row and then stop. Then do some of her more normal feeling pokes and prods to go back to a random shake 1 min or so later.
I am only comparing this to my last pregnancy and my son never did this. It has even woken me up sometimes. It's mainly when I'm lying down. I thought it might have been because she didn't like the position i was lying in or something....I don't know but I'm a worry wort and I'm freaking out that she is having a fit or something.
Have any of you had these type of movements?
