Hi!
I started feeling some movements at about 20 weeks but no kicks. I only felt the baby moving when doing some activities like cleaning, washing up etc... baby does not like it when i move too much and i can feel a strange sensation like something rolling up and down my belly, whcih is my son moving(i suppose lol)
I realised the kicks when my gp listened to his heartbeat and she was telling me, here he is kicking and realized that the feeling i had (it is like when your heart is beating so fast you can feel all the pumps of it) was the baby kicking. But otherwise it has not got stronger, cannot tell with what he is kicking or anything, it is still very light!!!
