Thanks everyone! Sorry things didn't work out for you this time, @Annerley. If it's any consolation my FS says that most women who have a chemical pregnancy go in to have successful pregnancies in the future. Still, I think the more you experience the different ways things can go wrong the more nerve wracking this whole process is - that's certainly what it's like for me, anyway! I really hope that the next cycle is a better outcome for you.
