It's very different for everyone. I think for me it was 12 weeks I felt flutters. Your weight, the position baby is in, the placement of the placenta, and how active baby is all play a role.
With my first I was 21 weeks now I'm on my sec I feel alil movement here and there and I'm 18 weeks
I've had flutters since about 16 weeks, now I'm 18 weeks and they're starting to feel like kicks now. The more it happens and you focus on what's happening i think you'll be like ahhh that was baby :)
I didn't feel anything until 19 weeks. Now it feels like Alien is gonna bust out of here. lol
I started feeling flutters at 19 weeks,nearly 21 weeks now and can feel full kicks.
They start kicking and moving in the first few weeks, but when we actually feel them varies person to person and whether it's your first or not. This is my first baby, and I definitely felt weird bubbles and vibrations from about 14 weeks, but was never sure what they were. At 18 weeks I felt spasm feelings in random areas which must have been kicks. Then at 20 weeks I actually saw my belly move and my partner felt him too!! It helps to know where your placenta is too, which they told me at my 20-week scan. Mine is at the back and high up so I can feel lots of movement. I know people who have their placenta on the front and feel kicks much less.
