Need help possible evap?

Kathy
So my period was due today and its a no show I had cramping a week ago which is not normal for me. So today I went out got a 88 cent first signal test and I gave it 10 min I thought I saw a light line but wasnt sure well 3 hrs later I look at it and its like this and its like purple so it has color like its supposed to. I've always used these tests and never had them dry positive but I have 3 like this. Do u think its a evap or a BFP?
