What do you call being excited and scared at the same time?

I had a tubal pregnancy back in March and had to have surgery... Lost my baby and my left tube. Took this test yesterday, (exactly three months after my surgery), trying not to get ahead of myself with excitement but kinda failing at that! I'm excited but very scared it might happen again! I was only 5 weeks along then. Now I'll be 5 weeks tomorrow. First appointment isn't until July 21. Hoping to find our rainbow after the storm we've been through! Supposedly from my last period, my due date will be March 2!
