Faint lines & feeling faint!!

Carly
Ladies sorry to post again! But need advice....
I'm only 1 week post ovulation (crazy to test so soon I know) but got a faint line yesterday & this morning with my first wee (TMI). The lines were just visible before the 15 mins but I can def see them now - does it still make them invalid? I'm not going to tell my husband until I know for sure in a week or so so I've not got anyone to ask. 
The top test is this morning and the bottom test in around 6pm last night xxx
