I'm no expert, but in my case my levels where really high. So high, they did not think it would be a healthy pregnancy. They tested me again a few days later and the level was more normal. I was told it could have just been I was tested "at the wrong time" - - meaning there was some fluke at that particular time/moment/day I was tested. In the end, my pregnancy was fine.
I will keep my fingers crossed for you. It is a stressful time. I will be trying again myself in the near future. I worried for quite awhile, as well, and know I will worry just as much the second time around. Although, the worrying/stress does not help anyone.
Again, I will keep my fingers crossed for you.
You should consider going to the Baby Whisperer website. They have forums on pregnancy, sleep, naps, support etc.
