Confused

Brittany • 19. Engaged to the love of my life. Been together for 2.5 years. 2 amazing step kids. And a ftm , to our son who was born February 3, 2016. ❤
Okaa so I woke up to go pee. And when I wiped I noticed blood. I am 34 weeks 4 days. It wasn't a lot at all , in fact it was just like little drops like you get when you have a little cut or scratch. I haven't shaved yet so I know that's not it. I've never had this problem before and I know it may not be a lot but I'm still really worried. I am hours away from home and I won't be back home until Sunday night. I'm not sure what to do. Someone help? Should I be this worried? What could it be?
