Baby Kicks or Movement

Hi! First time here to be a mommy. I'm now 22 weeks and I am a little bit worried since I feel baby's kick non stop from 3am and it's now 10 am in the morning but still I can still feel kicking every now and then. Is this normal? I only have 3 hours sleep because of my baby's movement. I also feel bit of cramps. Please help. #pregnancy #firstbaby #advicepls #1stimemom
