My period was suppose to come on the second of jan. it did not come until the 10th of jan. it lasted 3days which is short for me. Since the 13th when the bleeding stopped. I have been having very sore nipples, strange... usually the nipple soreness is gone 3days before the period is finished.

It may just be an off cycle for you. You could try a pregnancy test, and see what results you get, or wait until next month and see what happens with your period.
