answer me this...

i thought my period started on monday. i had moderate cramping and brown discharge. it threw me off because my period normally starts very heavy. this was light. it also is normally very red. very bad lower back pain and severe cravings. also very fatigued, more than normal.

then, yesterday, it was even lighter and was a red/brown color. i has light cramping and then cramps were all gone by 5:00 pm. the lower back pain was still there.

today it stopped all together mid day. no cramps or discharge. the lower back pain has stayed.

my periods or normally, at least, 4 days or more. nothing was the same as my normal periods are.

thoughts, please?
