Laughing a lot, will it be okay?

Yuta
Hi all, was watching some funny show with my hubby yesterday and it was really laughing a lot like to the point where your tummy starts to hurt.  I felt my belly and it was hard and a little painful from laughing so hard.  No bleeding, nothing like that.  I'm 16 weeks and this is my first pregnancy.  Any thoughts as to whether this is fine, no big deal or maybe an issue?
