Line after timeframe?

🤦🏼‍♀️ I took this test this morning with FMU. I watched it within the timeframe and there was nothing. I left it on the counter in my bathroom and when I went in there about 45 minutes ago there’s now a second line with some color (has more color in person). I know this is probably either an evap or indent. Just wondering if anyone has had similar experiences and what their outcome was? My period is supposedly 4 days away. Hubby and I DTD during one of my peak days. Having tender breasts and also some pelvic pain. Thanks ladies ❤️.
