💕can I get a little help💕

Hey guys 💕 I needed some help because last time I was on my period me and my s/o did the deed ( i know, I know it's weird but u won't know till you've tried) anyways he had cummed in me and I'm not on any form of birth control but we went and bought the morning after pill ( those things are so expensive 😑) my period started to be not as heavy. I expected that. But fast forward to this period, it's late by 2 days (it's 12/21/16). So has anybody been through this? If so can u let me know what to do! And I did check the sides effects and it said my period can be late by a little but u just want to be on safe side 💕💕💕 xoxo
