Cravings! OMG

I'm 31w 4days and craving sugar like a mad women!! Before pregnancy and during most of it I never ate any added "cane sugar" or "sugar" I've always been more of a savory flavor fan. But all of a sudden I want to buy a can of frosting and eat it! I want cake! Lol it's so not like me!! I'm trying so hard to fight the cravings and substitute with a healthy plain yogurt with some honey and fruit but my brain is NOT satisfied with my trickery!
