Evaporation line??

Karen

So I’m on the Mirena IUD for 11 months, But lately I have been experiencing pregnancy like symptoms, Such as, dizziness, nausea, hella tired all day, heat flashes, mood swings, TMI but I have been a lot more horny ad well, With my other pregnancies, I would get super horny in the beginning, and some times randomly my breast get tender. Also, I would literally bleed or have spotting every other week since the IUD and now I haven’t had any bleeding or spotting for about two or three weeks. I decided to take a test after my workout, At first, the first line only showed up, negative, The second one never showed up, I figured I messed up and didn’t pee on it enough and left the test in the counter so I can just get another one tomorrow. This morning my husband woke me up showing me the test saying it’s positive. Is it an evaporated line, Or could I really be pregnant?
