That happened to me with my first when I had a urinary tract infection
Also could be baby hitting a sciatic nerve.
You're welcome. My baby did that a lot when I hit around 24 weeks when she started to get bigger. I thought it was contractions. But she was just laying on nerves. If it was contractions you'd feel pressure and if it was braxton hicks you would feel tighting. Switch position to get her to move :)
Oh I switched and she moved real fast lol
