So February 8th 2013 i started my period and it lasted till Feb. 13th it was not like my normal period. My flow was very light and usually my periods are extremly heavy. Now Feb 19th Im spotting again. The color is in between brown and red. Ive been experiencing nausea off and on before today and headaches and sleeplessness. Ive been having a hard time falling asleep and dealing with body pain and headache. I don't know if any of this has anything to do with what im asking, but What does it mean? Why am i spotting when i just got off my period about a week ago?
