TMI no picture tonsil stones

I have had tonsil stones all my life but they have gotten so much worse since pregnancy. Here is the TMI part... I just pushed one out that was the size of marble... I threw up after. I figured out a couple of years ago that when I eat chips I get them. I think it happens with some crckers too. Does anyone have any advice for me? I see my OB tomorrow and will ask her too. I am just so grossed out.
