18 weeks... is what I can feel the baby?

I'm 18 weeks and 1 day today. 
For the last few days I am sure it can feel pokes, some really light pokes and others really quite strong. 
Am I feeling baby? Everyone keeps telling me it's too early and everything I've read is saying the same. 
I feel these pokes more so after I've eaten.
I'm not sure I ever really felt that fluttering stage, I think I must have and was just unaware.  
What do you all think? Please give your opinion.
