7 dpo- I need your help

So I had light brown spotting on 4 dpo then it disappeared. Then today (7dpo) I wiped and it was brown discharge- both situations it was only visible when I wiped. I’ve also had sore breasts, headache, and congestion. This is my second month TTC but I’ve also been highly stressed. My af is suppose to start in 5 days. What do you ladies think?

It’s very hard to be positive about this when I know stress can cause issues. :(
