i would say its fairly normal , some ppl dont feel movement untill 22 wks ... have you tried drinking a really clod drink and lying down ?? also really feel your tummy , give it a shake and a prod .. and relax to see if you can feel bub ..

If you are really worried go see your midwife , call the hosp for reassurance .. they can put a doppler on and find bub in seconds ..

hope you feel bub soon , its most likely facing toward your back and kicking so you cant feel hin ..

let us know how you go xx
