I don’t feel hungry anymore and I’m pregnant. Help?

I’m 5 weeks and 5 days today. Yesterday I had a really bad craving for KFC especially the KFC coleslaw. I ate about 4-5 spoon fulls and ate 2 grilled chickens, mashed potatoes & gravy, and a biscuit with lemonade and it was delicious.

After 20 minutes I started having baby barfs and it mostly contained the coleslaw. This morning I woke up and I had mild cramping. I usually have really bad cramping when I have to poo and it usually goes away. But today, light/mild cramping and even on my sides. On top of that I didn’t not feel hungry and I only had one meal so far and I haven’t been hungry or craved anything ever since.
