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. eve 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 :)
