Have had faint lines for 3/4 days consistently. Same this morning with FMU. Had creamy discharge when I wipe for them last week, yet this morning it’s a pale pink/brown. Does this mean I’m out and they were false results? Or could it be implantation bleeding? Have sore breasts, fatigue, feeling sick, cervical/vaginal pains/twinges, cramps (not like period cramps though). Thanks in advance
