Pregnancy feelings

So I am 13, almost 14 weeks pregnant and I am just wanting to be as far away from people as possible. I am a full time college student, I work, and I do many of the household duties. At this point with family stress and my own emotions and not feeling great I just want to stay home for this holiday. Is it fair of me to ask him to change plans and to just stay home. I really don't want to go to so many cookouts and have people asking 100000 questions. Thoughts on how I can explain this to him?
