I would talk to her about it , I've had many miscarriages & right after one of mine , my sister became pregnant , and she was very excited , and even though it was hard for me to find excitement at first , I realized thats my sister and her kids will always be like theyre mine ,i put my feelings aside & was very excited for her bl& but I definitely didn't want her to think she couldn't talk to me about one of the most exciting times in her life bc it can become a stressful situation for mommy and I surely didn't want her to feel distant from me in any way possible ,

I will ask her. I don't want her to feel like I'm rubbing it in her face the last thing I want is her to feel like I don't care about her only myself

If y'all are close maybe sit down and ask her if she'd rather you not talk about yours for a while or if she wants to hear about it so she can make the decision on how she feels?

Tell her your sorry for her lose and ask her if she is comfortable with talking about your pregnancy
