Positive or Evap?

This morning I woke up around 1 am and took this test I didn't see a positive after about a min or so and ended up going back to bed. Well when I finally got back up at around 6 I went to wash up and was reaching to throw it away and I saw the faintest pink line. at this point I had previously informed my husband it was a BFN and we are used to it. Sometimes I leave them out for a couple of days and I've actually never seen an evap line before on any test tbh. I'm 9 days late have been on birth control to regulate periods but stop taking for a couple of days to try and ovulate. POCOS at it's finest doesn't let me ovulate. I've never missed a period on my BC progesterone only pills. My

family has a hard time getting positives when pregnant but I don't want to have false hope if it's an evap. They usually don't test positive till week 6.
