Ok so I had my periods the 15th of December until the 20th. On Christmas <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a>, December 24th I took plan B the morning after pill.. On the 30th of December I started to bleed is this my period again or is it a side effect from the morning after pill? I am very worried yet confused.
