HELP, TTC- AF OR implantation?

Dee • We first conceived in March of 2014. We were so EXCITED, we lost our baby & have been trying every since. This struggle has been devastating. Hope we conceive soon ;)
AF is due Saturday the 12th, have a discharge with a light brown tint to it, that's like school glue & thick. could it be implantation or do you think this month brought another BFN? HOLDING OUT HOPE FOR OUR RAINBOW BABY (Fingers Crossed)
