How can you tell if it’s an evap??

Jarah

I’m 7dpo. The first test was in the timeframe, the second was about 45 min later. I know I’m crazy to test this early, but I can’t help it. I’ve never had an evap line before, so I’m not sure what they look like. My last pregnancy that ended in miscarriage sort of started this same way. I took a test, thought it was negative, looked at it three hours later and it had a second line. I’m confused!
