My name is Lyndsy, and I am 17. My boyfriend and I have been dating for over a year now. He recently was in a car accident, and was put in the Intensive Care Unit. My period is usually about the 10th of every month, and lasts about 7 days. This month (January) my period was on the 23rd and ended on the 26. It was not heavy either. We did not use protection. My breasts have been tender, and my stomach feels different. Am I confusing myself? Or was I late due to stress of the accident?
