Cravings and constantly hungry

Is it just me or is it a way for my body to tell me that we need all that food? Every day that goes by I feel hungrier and started to crave sweets even though I like more savory and salty things. I stopped working a week ago to start nesting and prepare everything for the baby, but I'm afraid that all my efforts of not gaining too much weight in pregnancy is going to fail because of this 😂😂😂 I've already gained 15 lbs during pregnancy and there's still 2 weeks left.
