Tonsil stones ?????

Jessenia • First baby to be born on may 22, 2016
So I could barely swallow this morning and my throat felt extremely dry and my tonsils feel swollen I look in the back of my throat and my tonils are swollen with little white stuff and my tongus is white. Is this tonsil stones ? And if so I'm 11 weeks and 2 days pregnant is this common in some pregnancies ?
