Sparkly, honestly, who cares if you lose it with the nurse tomorrow? Look, you are human, despite how perfectly amazingly stoical you appear on here, you cannot go on having chemical pregnancies and for it not to affect you. My love, please cry tomorrow at the nurse. Don't hold back. Please ask her if you can have the beta blood test in future on the day you get your BFP.
I also suggest you start a thread here on MN asking for advice about all of this. Change your username if you feel shy or embarrassed or just nervous. You don't need to say you have been using AI. There is an absolute wealth of knowledge on here if you will just reach out. I can only suggest so much, and there are few others on this bus who will be able to give advice. Please use the wonderful advice out there
