A day period.

This isnt normal to me, on the 14 a regular period day and feom the 15th to the 17th i was soptting very light and it was pink and brown.

My normal is 4 to 5 days and 2 days spotting, but this month we had "fun" on the right days and im not sure if i am pregnant or not, because i took a pregnancy test yesterday aug 17th and it was negative.

Has this happened to anyone else that got a positive or got a negative?
