Hi I'm always having my period on the 12 or 13 but this month of January is different it's the 27 and no sign of my period, I took 3 pregnancy test when I was just 5 days late and all of them said negative but know my breast are hurting and getting swollen is could this be normal??

Your best bet would be to go see a dr as soon as possible. A friend of mine conceived but it NEVER showed on a home pregnancy test. She had to have a blood test to prove it positive.

Hope this helps.
