Everyone is getting sick...

Annelise • 24. Married. I have a 2 year old and 1 year old sons.
It's flu season but my mom has pnemonia an her bf has menangitis. I am almost 12 weeks pregnant an am so nervous about getting sick. Should I just stay away from everyone for awhile until they are all better? I've never ever been sick but now that I am pregnant I don't even want to risk it.
