Should I test?!

Hillary

So Monday, 4 days before AF, I had some brown stuff and thought oh AF is coming, then it stopped. Tuesday I had some blood so I was like oh here she is, it stopped that day. I have not had anything since and my original start date was 27th-28th. I calculated and it’s possible that it could have been late implantation but I don’t want to waste another test. What should I do, what are your thoughts?!
