Hungry as a Mother!!!!

I am 30+5 and honestly I did not have any sugar in my diet for the last 4 years until I hit about 25 weeks. And since then I have been nonstop cravings sweets and brownie sundaes OMG!! And now I can’t stop myself. I have been eating larger portions than I used to. I guess it’s probably normal but I gained 11 pounds in 20 days since I began to eat sugar again....I’m bummed because I was gaining so slowly until this. This kid has me eating terribly! Am I alone in this??
