Missed pill?

I am on currently taken yaz birth control. I have always taken my pills faithfully and just recently missed two pills. I missed tuesdays pill and had wednesday morning but my boyfriend withdrew before . I also missed wednesdays pill and had wednesday night and he withdrew again. I realized this morning i skipped tuesday and wednesday as i took both pills. Should i take the morning after pill just to be safe? I dont want to get preg are my chances real high since i missed two pills?
