Could you send her a text saying you're sorry her cycle failed and hoped she was ok? Maybe it will be the ice breaker she needs to contact you?

She is probably so caught up in her own emotions and grief she's not thinking as she normally would.

Although it would be nice to get a text I can understand if she's not thinking straight and engulfed in her own misery. Hopefully she'll surface soon.

Congrats on your pregnancy. :-)
This might be a nice way to do it... Truth be told, there is nothing perfect about it whichever way you deal with it.

I am so sorry. This must be very upsetting for you.

Sorry but I feel your SIL is being selfish.
Tegam, I can actually see where you are coming from - they may be in their own headspace and not thinking of anyone else, but I kinda agree with the others that it seems a bit harsh. When you are so distressed it's nice if people can try looking after you for a while - and maybe that's the place they are in - two weeks to not reply, and having a BFN in that time isn't really that long.

But of course, we all have our own opinion and that's understandable either way...

from my point of view - I would prefer friends to let me know by text or phone - BUT family and close friends, I actually think I would like the respect to be told to my face - by the person who is my sibling or friend, and to be allowed to cry and be sad if that's what happens. Cause I'd like to think that I will be calm and handle it with congrats and excitement, but I may have trouble with that, and I hope my family and good friends would understand.

after all - I am the one going through the crap, and it feels like everyone avoids you (totally understandable, cause how do you talk about it, when I don't want to!, but at the same time, I wish people were being nice and checking in and looking after me for a change. I always have to be excited and happy for everyone with their exciting news, but I can't share the crap news (cause that hurts to), and everyone kinda just leaves me alone.

Don't get me wrong I do understand, but I do wish people would... occassionally, just check in.
One of my good friends, every now and then, will just email me and say something like.... "just wanted to check in and see how you were going - not going to talk about anything "important" (unless you want to), but I wanted you to know that I was thinking about you xxx".

I really value that and appreciate it - she's not asking me to my face - where I might not be ready nor want to, but she is letting me know she is available if I'd like, and that she cares enough to keep checking in..... and you know what, she is the one who I do talk to, and want to talk to when I do see her.... those people who are 'respecting me' by not asking.... I don't know how to talk to them... cause I know they don't feel comfortable or know what to say. So I don't want to make them feel uncomfortable, and we all just pretend it's not happening.... and that's my sister I am referring to.

but if she gets pregnant - the nicest thing she could do, is take me out for lunch, by herself, and say..... "this is really hard for me to tell you, and I will totally understand that it is hard for you, but I need to tell you that I am pregnant. And I hope we can enjoy the journey together, but I will understand and and try not to get hurt when you can't be".

I think I deserve the respect to be told to my face by those important people - because if you love me, you can deal with my emotions for a while - cause I'm the one going through the crap - and of course, I will be happy for you, and you know me well enough to know that I will be respectful and happy for you as much as I can. But we all have our journeys, and we can only do what we can do.

I guess - to answer your original question - I too think she needs more time, I'd like to think I would text as well - especially if I knew you'd both been on the same journey, but maybe I couldn't, and maybe, maybe I do need you to initiate. I think in this situation your silence would be equally uncomfortable for me, as trying to formulate a text message that is congratulatory. Maybe she is feeling hurt that she hasn't had any sympathy for her BFN....

I think the text message saying simply...."so sorry to hear about your BFN, I wish there was more I could do and I understand our news must be difficult at this time. I am crossing my fingers your journey starts soon, so we can share it together. I am thinking about you often. xxx"
