What causes sore nipples you are not pregnant and you cycle is not coming on nipples are always sore?
Your question doesn't really make complete sense, but if you are
asking what causes sore nipples, other than pregnancy, then I have
one answer.
Sometimes, a week or two before my menstrual cycle, my nipples
are very sore to the touch.
If your cycle is not coming, it could be the result from stress.
I remember being stressed so bad, my period was delayed a week and
three days.
So it's perfectly normal for your nipples to be sore, especially
if it's close to your monthly.
