Missed pill + zero condom

On Friday I had a severe panic attack and cried for 17 hours thinking that I was "over" my boyfriend. The day before I was completely happy and everything was normal on the relationship front... I put it down to BC (Levlen). I've been taking it for 6 weeks now. 
Anyway, long story short, I made the concious decision last night to stop taking the pill as it was completely taking over my emotions and scaring the sh*t out of my boyfriend and I. 
Then we had sex. Without a condom. After me intentionally missing a pill... (I know, I know. My mind is elsewhere...)
If I take the morning after emergency contraception am I safe (ish)?!
