How do you deal with news of friends miscarriages while pregnant?

I’m 28 weeks now and in the course of my pregnancy, three different amazing ladies I work with each confided in me the incredible news that they, too were pregnant. And today I just got the news that the third one lost her baby. The other two also suffered heartbreaking losses over the last 2.5 months. I know miscarriage is unfortunately all too common but I just am so heartbroken right now. Each one is a reminder at just how fragile this little life inside me is and it’s hard to cope with it each time. There’s also this kind of survivors guilt, like why do I get to be the lucky one who’s still here pregnant? None of them deserve a loss like this. Just feeling upset and wondering how many others have experienced this. How do you balance the gratitude and joy from each of those little kicks that remind you your baby is still alive and well, while also dealing with the news of such painful losses of others, and the gnawing fear that there’s no guarantees that your baby will make it? Viability milestones are not guarantees. Hopeful, grateful, afraid, and heartbroken😭
