Morning after pill: levonelle

Rachel
So it must have been new years <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> and had unprotected sex, so not even 12 hours later I took the morning after pill. I then a few days later had a period which is normal apparently, but now 28 days later and my period is 4 or so days late... Did most people find this?
