Cravings!!!

I'm 4 weeks and 3 days and I already feel like I'm constantly hungry. Plus I'm craving spicy food and then I always want something sweet afterwards. My amazing hubby went to the store to get me strawberries and cool whip and made me jello for the cool whip also just because I couldn't let go of the craving. He laughed at me and told me that the 8 almost 9 years we've been together he doesn't remember me ever eating jello. My fisrt pregnancy with my son I craved spicy food and then healthy food like apples and peanut butter and salads(really anything with lettuce on it lol). Anyone else having weird cravings already?
