Is something wrong with my breastmilk?

As

my son is 6 weeks.

He is exclusively breastfed.

He is very gassy and hes been spitting up a lot lately. Hes also crying a lot.

Last night/this morning was awful. He cried non stop. He was super gassy, and spit up all over us, numerous times.

I am a vegetarian. I'm trying to avoid all of the gassy vegetables and I'm limiting dairy right now. Theres nothing I can think of in my diet that's causing this....unless it's the dairy.

Should I make an appt with the pedi?

Should I try something?

I'm open to all suggestions please
