This particular thread is for those who want to keep track of their first blood test every morning, but there are heaps of other threads, so have a browse through them and you'll be amazed at what you can find! And don't be disillusioned at your husband's levels at this stage - using what you'll learn on this site you will see those drop surprisingly quickly.
Meantime, I'm tagging
