Just to add, a similar thing happened to me too
my best (and pretty much only) friend of over 15 years just stopped contacting me a week after she had her first baby back in February (I had my funding confirmed in January and told her then for the first time). I don't know if it was related to the surgery or not. It hurt like hell and it still does. And I'm going to stop there before i a) can't stop and b) start crying lol.
