Am I pregnant?

Hi everyone,
So my last period wnded on the 2nd of Feb and on valentines day and for the last two days I have had blood in my discharge which is like egg-whites (stringy or however you'd discribe it, I don't know), my boobs are beginning to get a little sore and also I have felt nauseous in the last day.
I don't know if anything anout this could signal pregnancy but I would love to have some opinions about this amd some help. I'm also getting a test tomorrow.
