8 months without period

Destiny • ~*Fiancé and fur mama ❤🐶💍*~

So a dear friend of mine hasnt had her period in 8 months. But now shes spotting. No cramping. Just spotting. She had ovarian cysts in the past but that was taken care of. Any advice i can give her. Maybe someone can tell me why this is happening. Shes been spotting for 3 days now. Light spotting. At first we thought it was bloody urine but she wore a panty liner and it was light red spotting. Can someone help me figure out whats going on...!!?!!??
