This is my first baby, and at the end of 17 weeks, I felt quickening for the first time. Now I'm 20 weeks and it's gotten stronger and more frequent. Everyone is different though!
I started feeling mine at 16-18 weeks, very small flutters, like gas bubbles and popcorn
18 weeks for me... now at almost 33 weeks, I can't keep his feet out of my ribs and they are very strong. Everyone is different and it also depends on placental placement.
18 with my first son 15 with my 2nd son:)
