my period lasted from 19-21 but it wasn't actually my period it was very,very light & pink wasn't enough to fill a pad or tampon & normally my period is heavy , after the spotting ending when I went to use the bathroom & wiped it was brown discharge but only a little and that only happened for about a day or so so today July 27 I took a pregnancy test & got a negative result is it possible that I'm testing to early ? did I have implantation bleeding ? I have been trying for several months now & I'm hoping to be pregnant ...

very tired duu
