Okay so I just finished my period 10 days ago , it's lasted a few days short than usual, but nothing too unusual . And yesterday in the morning when I wiped I had a brown discharge with no red in it at that time , then later that day when I went to the bath room there was a bit of brown and a little bit of red in my panties , so I used a tampon and over an hour I checked to see if I was bleeding and it had a little red , and over night I had light bleeding . I've never had this happen before ?
