The same thing happened to me with my 1st born. dedicatedrider hit it on the head. Give it some more time. I'm sure when you take another test, it will come back positive.
I was suppose to start my period, was 5 days late, took a test and it came back negative. So I thought I wasn't pregnant. I never had morning sickness but my nipples were very very sensitive so I just knew I was pregnant. I read the instructions on the pregnancy box and it said something about if you get a negative response back and you think you're pregnant, it's probably because the your hormone level isn't high enough to detect anything, blah, blah, blah. After another week or so, I took another test and I'm Pregnant!
So give it some time and let me be the first to congratulate you on your pregnancy!!
