yup. the movement from left to right is your baby moving. kicks lighter or lesser now maybe becos baby is just tired or lazy. sometimes when we r bz, we will not notice the kicks even though they have kicked. y not try to lie in bed and count the no. of kicks? the minimum a baby should be kicking a day is 10 kicks. if lesser then 10 kicks in a day or no kicks at all... better go hospital to check. if you r worried still... becos you feel there is lesser kicks, just go to your hospital n tell them that you want a check on your baby cos you feel less kicks and inform your gynae too.
i experienced what you have gone through few weeks ago. so scared... cos lesser kicks then usual. baby is usually very active. so terrified that i called up my gynae and she advised me to go in to delivery suite at Kandang Kerbau Hospital to monitor the baby. when at Kandang Kerbau Hospital, the midwife put me on a CTG machine which measures the baby's heartbeat and our contractions. n i was told to count my baby's kicks. all things went well. so its presumed that baby is just plain lazy for the 2days. he is now very active again.
things will be fine. just go for checks to have a peace of mind. dont worry. jia you!
