First feeling of nausea

Today is the first day I've felt nausea. I am 5 weeks tomorrow. I was eating these yummy chicken meatballs that I love. After eating 5 or 6, all of a sudden I felt nauseous and totally turned off by them and fed the rest to my dog! Anyone else feeling early nausea? I got some preggie pops but after I saw that they don't contain ginger, I'm wondering if something cheaper and sour like jolly ranchers would work also.
