What would you do?

I am almost 13 weeks pregnant with our rainbow baby, it’s also my birthday. I announced to my grandma early (at about 8 weeks? Although I know thats not early to some people lol) because she was going through a lot so I wanted to give her some positive news, plus I trust her to be there no matter what happens. She told me she wouldn’t say anything but the family has noticed that her memory and mentality isn’t the greatest. She has memory issues and sometimes she has a hard time making sense of situations. So she posted on timeline to wish me happy birthday but then added “I hope you feel better w the baby”. I messaged her saying that I would like her to delete it because we wanted to tell my aunt before a Facebook post. But she says she already accidentally slipped to her so she knows. I’m kinda bummed but I’m not super upset about it, especially not enough to make her upset. She needs to get surgery next month, she lives alone, covid really gets to her mental health, and when her and my uncle fought a few weeks ago, she cried a lot. So I just can’t bring myself to make a big deal out of it or be mad.

But now I’m not sure how to go ahead with announcing to rest of the family. We did dress up for Halloween to do announcement photos. So I’m wondering if I should just post them?
