baby wont stop crying- 3 weeks

since around 5 or 6 this evening, she wont stop crying/fussing. the only time she stops is when shes latched on. so ive been trying to keep her on the whole time but its hard to have a baby glued to your boobs all day. even after she falls asleep, ill move her but she wakes up so angry.

her diaper isnt the issue either. i tried a pacifier, it will stay in for a few seconds then falls out or she accidentally pulls it out. im gonna find her one she likes & one that fits well. hopeful that helps..

anyone know of any tips/tricks?
