Hungry and Hangry

Eva
I find myself getting so hungry so frequently! I had a fairly big burger out with the family today around 3:30pm and now (8pm) I find myself hungry again. It's like I never had lunch. 
Normally I would try and just push through it but now with baby (I'm 13 weeks along) I feel like I can't and I would be depriving it of food. Does anyone else feel like this??
