Faint line help!

Ive been having a few symptoms so this morning i held my wee all night lol and tested, a very faint line came up after about 1 minute, it says u hav to wait for 3 minutes so i kept watching and the line was gettin a little darker but nothing like the line next to it. I tried to take a pic but i dont think you can make the line out on the picture, i dunno what to do im scared to get excited incase im not but ive tested before and never had faint lines. But i obsess over symptom spotting, the past week and a half ive been feeling faint and going dizzy, extreme mood swings (but not sure if thats just me lol), i also had a migrane and my nipples where changing colour (but they do that before period) im also on a night finding it hard to catch my breath, and ive been waking up at stupid o clock i nthe morning (not sure if thats a symptom tho) and my knickers (tmi sorry) are really wet with discharge but its clear and doesnt smell. Please help what do you guys think. thanx Danielle
