Going on with IUI

We're going to continue with IUI, but it sounds like my RE wants to do at most only 2 more IUI cycles, then move on to IVF, I guess. Oh, and I still haven't gotten AF, so he said it would be best to do another blood test, just in case. Way to get my hopes up, again. And of course it's 6:30 now and they still haven't called me with the results. But I know it's going to be negative, unless being pregnant feels like you're about to get your period any second.
