yes they are normal, make sure that they are not painful
if they are not painful then, its just the way ur body is preparing for for the big day........
I am also 29 weeks, n been getting these very early.
Try to lie down on ur left side, n drink water, relax, listen to some music or just try to stay quite ........
u will feel better.........
if the contractions are painful, n intense then u need to call ur doctor
good luck
