HELP ME PLEASE!!!

Lyndsey

Been TTC my first child with my husband for over 2 years and nothing. But the other day I spotted for maybe an hour and it was extremely light. I didn’t even notice till I went to the bathroom and it was already done. And this was 15 days before my period is to show up. Took a test just to see if it would show anything and I seen a very very very faint line come across right away (or so I thought) cause now I can’t see anything. I am still 10 days before AF is expected to come. Yesterday I had horrible lower back pain and some lower abdomen and a few days ago I got this discharge. What do you ladies think?
