OMG, I was sick morning noon and night the WHOLE time. It did not always include actually getting sick but I always felt like I was going to. It was so bad I had to quit my job.
But...my labor was a peice of cake so that was good. A trade off I guess.
I hope you get your answer soon, as amystours said, if you have that "feeling" then it most likely is right. I knew a week before I took the test.
