Food talk...

Question for all of you who are pregnant! I am a little over 13 weeks pregnant...on some days I eat breakfast, lunch, & dinner with a couple snacks in between & I'm fine but then other days I am constantly eating because I feel like I'm starving & I also feel exhausted! During these days I seriously feel like the baby is going through a growth spurt or something lol, but really it is so annoying when I'm trying to eat healthy amounts of food but my body wants to eat the whole house...
