Okay so i had sex w/my boyfriend and he came inside me and i felt v nervous the day after and so he bought me the plan b pill. My boyfriend says that he is v low fertile, that if we ever wanted kids we'd have to go to the doctor, and that he's came inside his exes and they've never gotten pregnant. According to <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a>, my period is 4 days away and for the past couple days I've been waking up w/my stomach hurting. Does this mean I could possible be pregnant? I am v scared at the moment.
