EDIT- took another later in the day (same test) and it was neg.

I decided to take a test because after I eat now like throw up in my mouth (sorry gross I know) my period is due in 3 days and I am approx 8 DPO per the <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> (I was stupid and didn't tack ovulation this month because I'm sick of disappointment). I took this test around 8am and it didn't look positive so I threw it in my bag and pulled it out an hour later and there is a line... is it negative and just a random line that showed up????
