I started feeling kicks around week 20. Make sure you monitor movements regularly later on, and avoid taking sweet juices to trigger movements if you are checking your sugar levels.
For first-timers, it's around 20 weeks, but in your second pregnancy, you can feel it by 16 weeks. Don't worry if it takes a bit longer, every pregnancy is different.
My gynac said that the placenta position (like if it's anterior) can cushion the movements, so you might feel them a bit later around 22 weeks. Don't compare with others, just track it with your doctor.
