I've got tender breast for almost 3 weeks and had implantation bleeding about a month ago, sore throat for 2 weeks what could be wrong?

Dr. can check throat: Throat pain can be from strep throat infection (antibiotics are needed), a cold or influenza (antibiotics usually not used), or from some other cause such as allergies or irritants. Usually, a person sees a doctor if the sore throat is bothersome, recurrent, or doesn't go away quickly (mainly to see about antibiotics). Having "implantation" bleeding means being pregnant; doctor can verify that.
