Should I be worried about being out and about?

Claudia
I'm starting to feel uncomfortable leaving the house. My sister wants all the family to go out of town for two days but I don't feel like I should. One of our nieces are in town and now she's planning all these activities such as the zoo I want to go but I'm scared I'll end up in labor! What should I do? 
I have been dropping more and more everyday even I can notice it..
