My sister has one child (ds aged 4.5), and has tried for another baby for quite a long time. We have spoken at length/in detail over the past 3 years or so about the various methods she was employing - fertility drugs, various doctors/clinics, egg donor, well-timed/maximum fertility random sex, etc.
During those years, she has had one miscarriage (she regretted telling everyone she was pregnant too early as then she had to explain about the miscarriage). She also has had an unsuccessful embryo transfer using an egg donor. She is now 44, and our last conversation was about if/when she could accept the idea that she might not be able to have another biological child.
We have had extensive and regular conversations over the past 6 months as our Mother's health has deteriorated. I've visited several times, and we have spent a fair amount of time in each other's company.
This past weekend, her dh confided to a distant cousin that they are expecting triplets after treatment at a fertility centre which is a 3 hour plane ride away from their home. She is 10 weeks along, and has never breathed a word about this to me.
I am happy for her of course, as they wanted this for such a long time (though a bit at how she will physically and/or logistically manage triplets). But I am also hurt and even a bit angry that she has chosen not to share this part of her life with me. I also am very unhappy about how I found out the news.
I don't know what to say to her. I don't want to 'ruin' her happy news with my feelings, but am not sure I can pretend well enough for it to be convincing. Any thoughts/advice much appreciated.
