Hi I'm 20 years old and I've been on my period for over 2 and a half weeks now. I've got sore breasts which have got a little bigger. I had a check up at doctors not long ago and my pulse and heart rate are fine. What could be wrong?

Uave you had sex lately? You could be pregnant..

I suggest seeing a doctor. You could have a progesterone deficiency or thick endometrial lining. Without a physical exam, we can't fully diagnose you.

You really need to see a Gynecologist to find out for sure.
