So I've taken plan b quite a bit.. the last time I took it was twice in the same week.. I ended up getting my period. Everything is fine like I thought it would've messed my period up big time but the <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> app was accurate as to when I got it.. is this normal?? Could i be pregnant at all?
