So I'm 18 weeks pregnant and due (in part) to COVID, haven't told anyone the news yet.
My SIL is also pregnant and due end of July. They struggled to conceive and whilst she's nice, she's quite "precious" and an anxious person.
I'm not due until late November.
So when do i tell my family 
I'm worried that to do so now seems like I'm trying to steal her lime light of being pregnant... To wait until after she's given birth could also be interpreted badly... I could wait for ages (maybe September) but then everyone will be upset that we waited so long!!!!
Basically there's no "good" time....
Has anyone been in or seen a similar situation and has any thoughts / advice?
