implantation?

according to <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> AF is due in 12-13 days. was talking about college with my parents and thought "how fucking awful would it be if I got pregnant before I graduated". went to the bathroom and got this. i know there's not much, but is this possible implantation bleeding? I've never been pregnant before so I'm a little lost on what to expect with possible pregnancy. any feedback is appreciated!
