I'm not sure. I'm sorry, I'm new to all this. Never been pregnant before and have never really tracked my cycle. I do know that my last period started on Aug 12 with light spotting for about three days and then full on for about four/five. About two weeks after that I started getting sore nipples, cramps, stomach aches every time I ate. I never get any type of pms symptoms before a period. Today I'm having tan/brown discharge, very lightly and only the first time I wipe.
