In my 31 week of pregnancy, baby kicks are less than 10 per hour, what does this mean?

Lie on left side... To count kicks, drink lots of water, lie on your left side, and then do a kick count for one hour. If there are less than 10 kicks within an hour, one should contact the doctor right away to have the baby placed on a fetal monitor for evaluation, at the birth center or hospital. It is important to make sure baby is getting enough oxygen and nutrients, and that everything is okay.
