Morning after pill VS period

Hey guys, so I was due to have my period on Monday and it didn't show it up, Tuesday came around and again no period. Myself and my boyfriend decided to have sex and he came inside me (first time doing that but we've been using the pull out method), anyways.. We took a morning after pill and still no period today. Can someone tell me if this is normal or if I could already be pregnant and not know I'm to afraid to test.
