had sex sep 10-30 on& off no protection or anything . period suppose to be the 15 I'm a 28 day cycle  nothing comes no cramps no weird feelings then today on the 21 st I wake up to pressure got to the bathroom and was bleeding some then noticed already was stopping .
if it doesn't continue should I test ?

you could be prego but u also can have a changed period do to stress and stuff. id test to be sure and talk to a doc.
