am I pregnant or not?

I am 6 days late according to the app, I’ve felt nothing but sore boobs and being bloated after certain times when I eat, my discharge is white at point it was clear. I took a test last Monday and was negative. I took another one today may 11th and it says negative as well. my last period was April 8th. one of my boobs is bigger then the other one and has hard lumps. do someone think there is something wrong or if I should worry?
