Anyone else an emotional wreck?

Gracey Grace
I'm 7 weeks today! I'm so so happy and blessed with this pregnancy, but over the last week or so I have been so unbelievably emotional! Everything makes me cry, I'm so easily triggered and I'm getting so stressed with everything lately. 
Yesterday I burst into tears because my mum didn't text me back instantly.
What's the deal? Anyone else crying for stupid reasons? I'm struggling to control these emotions, my SO deserves a trophy for being so supportive.
