I had a posterior placenta, so I felt my first kicks at 14 weeks, and they felt like tiny little muscle spasms on my abdomen. They felt cute! Lol, then at18 weeks, it was full out dance party in there.
I felt my first flutters at 15 weeks. Just depends on where your plecenta is on how early you can feel definite kicks :)
I remember feeling my son move for the first time. Felt like butterflies in my stomach (:
Everyone is different, it is not "too early" it probably is because when I went in for an ultrasound I felt little flutters & bubble guts during the time they were showing me the baby move, it also felt like gas but it was the baby.
