I finished my period a week ago and now have sore nipples and tiny spots on the areola. they feel and look as though i am breast feeding?

Hormonal effects: If your period ended "one week ago" and your period is 5-7 days, you may be having a "double ovulation" which produces twice as much estrogen and progesterone, and the levels can mimic early pregnancy. These levels of hormone can have a temporary effect on your areolae, making them tender and slightly swollen. This is not abnormal, but if your next period is "late", get a serum pregnancy test.
