Hi, I'm 17 years old, I'm a virgin. However, I had a last menstrual period in the middle of May. I still did not get the next period. I had a pain in the uterus from the last period, but only every few days and like always before the start of the period. Breast pain also occurs every few days but again not as much as ever before menstruation. What could be the reason for the delay over a monthly period? I have always had a problem with a period from 15 years but there was no gap greater than 3 to 4 weeks. Looking forward to your help thank you
