I am a bottomless pit at 32 weeks 2 days?

I have been doing really well with my eating this pregnancy, but seems the past week I am starving all the time. I find myself constantly snacking and wanting to eat. I don't eat big meals, but have 6-8 smaller meals/snacks (eg: toast, carrots, apple, some cookies, sandwich, granola bar, rice cakes with peanut butter,yogurt, salad, chicken, rice all in a day) I just feel like I am always eating, I didn't feel like this with my first. My weight gain has been good so far (22-23lbs @32 weeks and I started 5'7" 137 lbs) but I am worried I am going to gain another 20 lbs before this last 8-10 weeks is up. Anyone else feel like this at this stage, and can I expect it to slow down? I know the baby is gaining a lot of weight right now, but I am just hoping I don't continue to eat like this for the next 8 weeks.
