faint line on pregnancy test

Hi everyone I'm kind of stuck here and couldn't find a simple answer to this online. I'm 18 years old and I've been seeing someone for over a year I was on the pill pill for a few months last year but stopped because I was experiencing low mood and spotting. So we have been using withdrawal and have been lucky enough not to get pregnant. I recently decided to go back on the pill but I've changed this time to marvellon. I was told that I needed to use protection for 7 days as I started mid cycle but we had sex 2 days after I started the pill using withdrawal put I'm not sure he pulled out on time. This had also happened earlier but not around ovulation.
Looking on my calendar it seems I ovulated that day I took a first response test and it seemed negative but when I looked closer there was a faint line. I tested 5 days before a missed period (it claims it can detect 6 days early). 
Do you see it too or am I going crazy / the focus on my camera is not so good so I put one in black and white? 
I need a second opinion my friend said she saw it but it's too faint to be a positive. My period is not due (bc of the pill for 3 days but would normally be due yesterday so I could test again soon but don't wanna waste money uselessly)   
** I forgot to add I am also having a lot of symptoms but they could be put down to starting a new pill: very sore boobs, cramping, slight nausea etc
