What is this?

So this morning I was just laying in bed and all of a sudden I feel pressure in my lower stomach so of course I touch it to see what it was and it felt like a really hard oval shaped thing coming out of my stomach. Im almost 16 weeks. Was this the baby kicking very hard or something else? Im really curious to see if anyone else has experienced that.
