Can an evap line happen if the test was taken ten to fifteen minutes ago? I haven't had a period because I'm only 7-8 weeks PP right now, but we had unprotected sex (withdrawal method 👎🏻)about a week or so ago, so still super early to test. This looks fishy to me. It's hard to see in the pic, but kind of want opinions? I don't want to run to the store again to grab another test. I'll run to the store tomorrow, and test again tomorrow. The anxiety is killing me!
