Second Period Missed HELPP

Dy-Asha • 21👑
I took 3 tests. 2 negative and 1 Faint Line. According to <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> I am 24 days late and that makes it my second period I have missed. I am sexually active, my boyfriend and I have not used protection since May 2015 ( the last depo shot I received) I have been stressed a little but not to the extreme. I just need some answers 😟
