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 graduate". (I graduate June 2018.) went to the bathroom and this is what I got. I've never been pregnant before so I don't know what to really expect with possible pregnancy.and feedback is appreciated!
