Abdominal pain?

So today around 3:30am Monday morning, I took a morning after pill because the condom my significant other had on broke. It's about 5:02am on Tuesday and I'm having INSANELY painful lower abdominal pains. I've ha pains from morning after pills before, but these are so my worse! I don't know if I should just let it do its job or if I should go to the ER. They just hurt so bad. I'm literally curled into a ball right now on the verge of tears because it hurts to move a lot.
