okay so i think i maybe could be pregnant but i’m not sure. he’s never came inside me, and i’m on birth control. i am on my inner circle of birth control which usually always means that’s when i start my period, i have not gotten it yet and i am two pills in, however this app <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a>, says i will start in two days. i don’t know what this could mean, should i be really worried??? please help
