Hi, I went through your query and understood your concerns. Mucus secretion and spotting (implantation
bleeding on day 17) are early signs of pregnancy
. Pregnancy test turns positive towards the end of the cycle. I would strongly advise that you repeat the test after some few days. If it is till negative, then you will need to see your Doctor or Gynecologist for proper evaluation.
I hope I answered your query. I wish you good health
