Nope, definitely not too early. I felt it very slightly the first few times around 13 + 5/6 and early in 14 weeks. I really wasn't sure of what I was feeling, but then it started up all the time from 14 + 5 and I would feel baby all afternoon and evening most days. It was really down low in my pelvis, just above my pubic bone at first, so really easy to feel. Now baby is moving up more so I don't always feel it as easily (probably because there's a bit of fat around my waist higher up), but it's still definitely noticeable. Just be aware of it when you feel it and what times of the day and then one day it will just flip on like a switch and you'll be feeling it all the time!
