I just googled it Hunni - found this:
Nipple Changes
Your nipples may become larger and darker as your pregnancy progresses. You may also notice small, goose bump or pimple like white areas on your areola. These are normal. They are called Montgomery's tubercules.
It was related to early pregnancy signs!!!!!!!!!!!!!!!!!!!!
also,
this was a definition of the montgomery tuberlces:
Definition: These are small goose bump like raised areas on the areola of your breast. This is not an additional nipple and is not a problem. This is considered a possible sign of pregnancy. These small bumps can be found in varying quantities from a few to up to thirty. The number may vary form breast to breast and even pregnancy to pregnancy.
These small glands are thought to be protective of the areola and help keep it healthy during pregnancy and lactation. You should simply rinse the breasts with clear water and avoid soaps and oils which can irritate the great tissue, this is particularly true in breastfeeding. This is one of the many changes you may notice in the breasts during pregnancy and one that will be helpful at maintaining elasticity in breastfeeding.
Many women worry about these or try to pop them. This is not necessary and can be painful or cause infection if you try to pop them. Simply leave them alone. If you are concerned about them, ask your doctor or midwife for more information.
Fingers crossed!!!! Have you done a recent pregnancy test just in case??
