5 weeks 2 days anger issues

So this is my second pregnancy and during my first I don't remember being so angry and emotional all the time. Now everyone and everything makes me angry and I get really snappy over little things. I have very little patience with my daughter and my husband. It's like they can do nothing right. If I'm not super angry then I'm feeling weepy and ready to cry. I never expected this to happen so early during pregnancy!! Is there anyone else having these kinds of emotional issues?? Or am I just going crazy??
