Can you become lactose intolerant

Ahrrianna • I'm Ahrrianna & 28. Married 10 yrs. Have 4 beautiful kids on the way! IG: quinncharger15
I'm 21 weeks but noticed that ever since I came into the second trimester I've noticed that whenever I have milk even a small glass my stomachs gets upset.
Is it possible to become lactose intolerant during pregnancy? Would suck because it been one of my cravings to have chocolate milk 😩
