Hormones hitting hard.

I don't know what it is about today, but it's seriously been the hardest day of my pregnancy by far. It started like normal,except when I had my saltines and ginger ale I couldn't keep it down. Then when my shirt for work was still wrinkled I just cried. I've just been so sensitive today. Has anyone had one day hit and it's just for sure that you're hormones are raging and everything is a bit harder and more exhausting than ever? I guess at least I know this is a healthy pregnancy?
