S.O.S

Okay to start off . My last period was October 2-8 very heavy . Normal as usual . October 31st , I started spotting Halloween night and it was brown very light I put a tampon in just in case . Hardly anything the next time I went to change it so I didn't even bother . Well same the next day . Mind you it was only like an hour if that that I spotted ? Well anyways my period wasn't due till the 6th of November . I didn't start . Haven't started . And I don't feel like I am going too . I have been having some cramping it's been mild not to bad . And I'm extremely tired . I have taken about five pregnancy test all negative ? WHAt is really going on ladies ? Any idea ?
