Tonsil stones while pregnant?

Shiara • Im an 18 year old FTM, engaged to the love of my life, the beautiful man who gave me my perfect little son 😍 15/18/16💙
Hey ladies! So im 31+5, and this morning i woke up with a pea-sized yellowish hard thing in my mouth.. Because of youtube, i know it was a tonsil stone. I looked in my mouth and i have another one forming but i cant take it out.. 
Ive never had them before, and im weirded right out! I read some google comments that say it happens in pregnancy sometimes because your thorat and sinuses swell (and its allergy season atm) Has anyone ha tonsil stones JUST in pregnancy
