Last week I got my period for one day, and then 4 days later I had light pink spotting only when I wiped only for one day , now I just don't feel like myself, my boobs are so tender, I have had a high fever for the past 3 days, any advice?

There is a good chance you might be pregnant. I think you should take a pregnancy test and see ehat happens. If it results negative and you still feel the same or worse go to the doctor and get a check up.
