Evap line or positive?

Alright I gave birth 11 weeks ago, at my 6 week appointment I got the ParaGard IUD. Since then me and my husband have been sexually active on a semi-regular basis. The first couple weeks it felt like my IUD was too low, I could feel the hard part of it, and I thought my body might have been rejecting it. But it’s definitely in place now, I can feel the strings where they should be. I haven’t made an appointment because I, myself, am a GYNO surgical technologist so my midwife trusted me to check the strings. I took this test and for about 3 minutes waited and it looked negative, I had to leave to drive my mom to catch a flight. I got home about two hours later and this is there. I’m freaking out a little bit because I thought evap lines don’t have color, just grey. Has anyone had an evap line look like this?

I took the test because I’ve been nauseous just like I was with my first baby. My milk supply dropped suddenly but I thought it was because of stress, and I have also been incredibly bloated and crampy. Let me know what you think.
