Ofcourse your not unreasonable to want a congratulations. If I was them I would have sent a text message. I'm not sure what you should do if you don't get a congrats from them, it's delicate but that doesn't mean your miracle should go uncelebrated.
With all due respect Rosey, you don't know what you would do unless you've been in that situation.

The grief from IVF failure is horrible. It's not just another BFN. It is THE BFN. IVF is a last resort for many and for almost half of those who go through it, it never works.

I agree your miracle should be celebrated Bloom. But they also need to mourn their miracle that never came.

Congratulations on your pregnancy x
