Pregnancy scare!

Alyce
Hey ladies, 
So, my S/O came in me 3 times during my fertile window and I took the morning after pill after the second time but I haven't bled? Every other time I've taken it I've bled within 3 days of consumption. 
Also, I was due 2 days ago and my period hasn't come. And I don't feel any cramps or anything. Only thing I've noticed is sore, swollen breasts. 
I could be stressing myself out but I always get really nasty cramps just before I'm due and the first couple days but....nothing lol. 
It's too early to take a test, I know. Should I just wait it out? 
Thanks :) X
