Brown spotting

It's been just over a week and I've been getting a brownish spotting. It's not enough bleeding to be considered a period but it's a little heavy for spotting. <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> says I was fertile all of this past week so I was assuming it was ovulation spotting but i'm not positive. I am sexually active but we've always used a condom and never while I was "fertile" tbh we've only had sex about 4 times ever so I'm not sure. But please lmk :)
