I'm 5 weeks 1 day pregnant, is it normal cramping and breast hurts. is it okay if i'm eating sour foods?

Probably normal: It is normal for breasts to enlarge and become tender in early pregnancy. Cramping may also be normal but in some circumstances it can be a signal of something more worrisome. For example, cramping on the right or left side can be a symptom of an ectopic pregnancy. Cramping associated with bleeding or spotting can herald a miscarriage. Eating sour foods is ok if you have good nutrition.
