I thought I'd seen the end of this category. But no, got to resurrect it because it's not over until the fat lady gives me a beta hcg level of less than 5. And yes, the level was five. I said to Dr ICU that he should speak more slowly when he leaves messages on people's answerphones. He said he'd take that into consideration which was nice of him. He also asked me how many IUIs I'd had, which showed a little carelessness since (i) it indicated no one had bothered to get my file out this morning, and (ii) it's proof positive that the doctors don't remember us as he's the doctor who did the pre-transfer consult with us and told us about our lovely embryos. Oh well.
So, as Susan predicted (unfortunately from personal experience), the story is that if the level goes up, it is almost certainly an ectopic. If it goes down, it shows that the poor embryo tried to implant but was too defective to get anywhere, as Summer suggested. So for heavens sake please let it go down. Having an ectopic really would be the final kick in the teeth to this stressful and somewhat pointless cycle.
