10dpo today. I've been having on and off cramping. I took a clearblue early detection test yesterday afternoon and there was a vv faint line straight away which has since disappeared as the test dried up. Took one this morning with FMU and it came up with a faint line again but a little bit darker than the one yesterday afternoon. Also took a red dye IC (same sensitivity) at the same time and it was negative. I've had this with these tests three times now, always have faint lines that have colour to it and end up coming on my period
. Do you think this is a positive or is it an evap?
