Faint line but increasing bleeding

Hi,

Help please!

AF was due on Thursday, very light spotting. Yesterday a slight increase but definitely not AF but over night it has increased. Still not my usual flow or cramping etc but definitely red - I read that pink or brown would indicate implantation but not red.

I took a test yesterday and the was a very very faint line, same again this morning.

We’ve been TTC for 3 months now and hoping beyond hope that the lines are going to increase in strength!

Has anyone else has bleeding like this and actually been pregnant? When should the line begin to darken? Or am I just hoping for things that aren’t there??

Think I’m around 14 DPO
