I would definitely go get checked .. I don't want to worry u but the same happened to me and the outcome wasn't good... so just to be safe I would have it check out as soon as possible... I'm not trying to scare u I'm just speaking from experience better to be safe then sorry
I'm sure its fine and yes I would say it's normal. Babies have down time too. As long as the kicking has only slowed but not to almost not at all or stopped completely. If you want drink some orange juice and Lie down to see if he gets going. Remember the space is getting smaller for him as he grows so he can't move as freely.
Any change in fetal movement should be checked!
