Day After pill??

I'm sure many of us have taken the "morning after pill" but my question is.....has it made anyone's period super late?

I took the morning after pill on September 29th and 2 days later I started to bleed again and then it stopped after 2 days. I was supposed to start on October 20th but nothing has happened. I don't feel any different just really worried here. Please help a girl out. 😫😥
