My little boy does the same thing. It is usually just because they don't like the position your in. When I was pregnant with my girl, she hated if I laid on my back and would literally kick me till I moved. Lol.
With my boy, if I roll on my left side, he'll kick at me for a few minutes, realize I'm not moving, then I'll feel him move and get adjusted. Lol. It's crazy that they already have their little personalities while they're still in the womb!
I would say yes I'm 36 weeks plus frew days and every time I go for a ultrasound if they need him to move they tell me turn on my left side make him uncomfortable but don't worry laying on your left side supposed to increase the blood and oxygen to your baby. So it's a plus :)
