Really confused on this one ..(tmi)

Okay SOO I really thought AF was here ... I woke up this morning with. Sudden gush of brown tinted cm . Light cramping (nothing major) I put on a panty linner and there was a few more drops of blood . Still light and the color was brown, I put in a tampon expecting AF to be coming full force shortly .. We'll I left went to eat and to my moms then about four hours later went to change it and it still only had a tiny bit of light pink /brown on it . I checked my cervix and  there was watery cm . I'm cramping , but on Sunday I was cramping and it lasted like 30 mins or so . This cramping is mainly on my left side .. I cramped with my first pregnancy but never bled .. I had an appointment with my obgyn in the sm but I rescheduled it due to "aunt flow " or so I thought .... ??
