Extreme hunger??

Hi! I am 4 weeks 6 days today. Anyone else experiencing extreme hunger? I feel like I am starving all the time. I've also been feeling really cold, anyone else? I constantly need a sweater or a blanket and it's like 70 degrees out haha. I tend to always be cold but this is definitely exaggerated.
