Confused ????

Nienie • Been ttc#1 since dec 2013 been with fiancé for 5 years :)
Usually my periods last about 5 to 6 days.  This month period was supposed to start on the 3rd , the day comes and usually the day af shows she shows in the morning soon as I wake . But on the 3rd at 11:00 at night I start getting brown discharge and the next day I spot pink all day didn't even fill up a whole pad. It never really got a bright red , more pinkish and brownish if anything. Crampin kinda and pains goin through legs. Idk what to think.
