Nervous.

So, I am 14 weeks 5 days. My grandma who was supposed to be my dula when I gave birth is going on a cruise with my aunt who was my back up the same week I'm due! I feel like puking every time I think of it those two are the only females in my family other then me. I am so terrified to have my first baby with just me and my husband. Ugh I just wanna puke any words of advice you mamas can give me?
