Comment PLEASE !

I took this around 915 tonight , and I thought I saw a very faint positive. But I threw it away cause I didnt wanna get my hopes up then about 30 minutes ago I pulled it out of the trash and it was darker , i have never personally had a evap line on tests I've even had for days.. but I dont wanna get excited for nothing.. is it a evap line ? I was supposed to start my period according to this app but my periods are very irregular so I'm not sure what to think.

Should I test in the AM ?.
