Feeling baby with hand at 18w

So earlier this week I started being able to feel the baby kick and move from the outside. My husband even felt it last night. I started feeling flutters and movements at 12-13 ish weeks. I heard a lot of people say that that is too early to feel anything and I was wondering if anyone else is feeling definite movement from the outside this early or if I'm really further along. When I went in the firsr time they did a dating scan and they moved my due date back 2 weeks from lmp due date.
