Jada, if both of your breasts itch, you might have some kind of skin condition like eczema or a fungal infection.  These are common in warm weather.  It would usually take more than a week or two for home remedies to work.  If you don't see a visible rash, you could try home remedies a little longer such as warm, not hot, water and extra rinsing to make sure there is no soap residue after your shower.  Spend as much time as practical wearing loose clothes without a bra to give your skin a chance to breathe.  Long-term use of any kind of over-the-counter medicinal cream without talking to your doctor is not a good idea because the cream that helps one condition can make another one worse.  This article on rashes in the breast area can help you determine whether you need to call the doctor right away.
