Is this a positive? I'm sooooo confused

So after coming on my period on Monday but it being much lighter than usual, then Tuesday light again to Wednesday and today being spotting 😳I have felt sick and dizzy all day so I took a pregnancy test after work, which showed up the faintest line unless I'm imagining it, so I took another with urine 30 mins later . Top stick is the first photo 
 hich is now not showing up any line 😳😳😩 so confused
