Increased appetiate

I’m 14 weeks and my appetite has increased tremendously. I use to go 4 hours or more without feeling hungry, now it’s more like 2-3. I’m worried about eating to much and gaining to much weight. I ate dinner tonight around 6 and my stomach was already feeling hungry at like 7:45! It wasn’t a very filling dinner so maybe that’s why I didn’t last to long without feeling hungry again. But I’m worried about weight gain. Did anyone else noticed a increase in appetite around this time? I don’t remember feeling this hungry so soon with my first.
