has anyone else experienced.. (tmi)

wondering if anyone has experienced something similar and gone on to have a positive hpt? my period was a day late (usually I can time it down to the hour), and has been incredibly light. initially there was bright red blood but now is more pink. I usually have cramps and I haven't had any since early early this morning. I'm still a little nauseated, sore/darker nips, tired, gassy, that hasn't changed since my period started. I'm not holding my breath, but I have heard of women who have a close to normal period and still get a positive hpt?
