So confused..

So I'm freaking out a little, my period ended on the 29th of last month, <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> says this is my last day of ovulation and for some reason I am bleeding, I've only ever spotted once in like middle school like 8 years ago...so I'm a little concerned...
