My last period was January 18th , my period lasts between 4-7 days and about 45 days apart, Iv taken multiple pregnancy tests all negative, about 3 days ago(April 6th/7th) I started having brown discharge, pinkish and brown stringy blood. Had sex w/ my husband April 2nd. Ushually when I'm gonna start my period I just have regular red spotting a day or two before I start not brown discharge, my boobs don't really hurt, minor cramping. Is there a chance I could be pregnant or early pregnancy or am could this be my hormones just messing with my cycle.  Feedback, comments, advice??? Thank you! :)
