3 week old getting angry and agitated

Marie • Hello, my name is Marie, I'm 27 years old and I joined this website the moment I found out that I was pregnant. This is my first pregnancy and I'm praying for a 100% healthy baby boy or girl 😊
Okay Idk if this has anything to do with this but I ate a bacon cheddar cheese burger with Swiss, mustard, Ketchup, and relish then I breastfed my baby. Ever since then he's been Latching on and off and being really angry and fussy. I want to cry because I don't know what's wrong but what can it be? He's not crying he's just really really agitated
