Random spotting?

Just a question: my period isn't due till next month, already had it this month. I'm not due to start ovulating (according to about 3 apps I use) till tomorrow or Thursday, but I think mines earlier than they predict. My husband and I have been actively trying semi regularly but yesterday I had pink spotting, followed by some brown spotting today. Is this a good sign of possible implantation? Or am i just crazy. We don't want to waste any  ovulation tests or pregnancy tests just in case because it's verrrrry early, and we are just leaving it up to God's timing.
