5 weeks 1 day and hunger doesn’t stop!!

Hi ladies I’m so worried on gaining so much weight, with my daughter I was nauseous the first 3 months.. I lost 10lbs before they prescribed me Zofran. This pregnancy I can not stop eating, I’m so hungry… I’ll eat a meal and an hour later I feel like I’m starving.. I’m already overweight so I’m terrified.. please anyone help, anything to calm down my hunger? Does this go away???
