Period is late :(

Hey Girls, I'm having an issue here... So on February I had sex without a condom 2 days before my period was suppose to come. The next day I took the "next day pill".

But instead of coming on the next two days, it came after 1 week.

This month my period was suppose to come 7 days ago and still not here...

I'm actually worried about pregnancy, and I'm a coward to do a test. Is it possible to be pregnant and after a week have period??

PS: I used to take anti conceptional pills, but I stopped 1 month ago and I started taking them again, about... 4 days ago.
