No AF brown discharge

Maggie

hey ladies, AF was supposed to come today but she hasnt. I have had a very light mucasy dc (only when I wipe and very light) that has a brown hue to it. I tested Tuesday with a generic brand test. (negative) my hopes are low because we have been trying to conceive and last month my period was two weeks late. anyone have any advice? has this happened to anyone else here and what was the outcome?
