I can't decide if I want children.

Ok so I've been with my husband for 6 years, married for 2. Pretty much the only question we ever get asked is "when will you have kids" and I always thought I wanted kids. Like so much so that we tried for about 8 months. But then I had to quit my job and we decided to put it on hold until I found a new job, but now that I'm working again...I'm starting to have doubts about having kids at all. All I can think is "I won't have any alone time, they are always sticky, THE NOISE." And it really turns me off to the idea of kids. But obviously every mother I talks to says "I wouldn't trade it for the world, they are my biggest joy in life" so. I guess I'm asking if anyone else feels this way? I honestly don't even know what to think. Help?!
