Vvfl or evap?! Help me?

Hi ladies, please help me! My husband and I have been trying for about 8 months. Today 10dpo I took a test the dollar store one, I looked at it for like 3 minutes and tossed it because I was frustrated it wasn’t our month AGAIN. This evening I look over and I see the line! I got so excited then started looking up how it could be an evap line I WISH I WOULD HAVE WAITED LONGER before tossing it! I had a clear blue digital saved for a rainy day but as you can see it says NOT pregnant 😢😢😢😢 has anyone had a BFP after something like this? I don’t feel much different then I normally do before AF comes so I’m just not sure!
