The First Kick

i forget when but i think it was 15 or 16 weeks like that. it felt like a heartbeat and when i lie down on my stomach it felt like a hard push.everyone is different. some happen early some late. some dont realize it while to some its actually gas. so from my experience its best felt where the kicks are strong which is in the 21 weeks. thats why normally people start to count the baby kicks when they are in the third trimester where its much noticeable.
