My friend just lost her baby when I had my rainbow.

I finally had my rainbow baby after three miscarriages (one set being twins). I could not be happier with this blessing that we have wanted for so long. However, one of my best friends is now struggling to stay pregnant. She has also had miscarriages and just recently I found out from a mutual friend that she had another loss and had to have a tube removed the same week as I gave birth. I don't know how and when to reach out to her or even what to say. I don't know if she didn't want to say anything to me because she thinks I'm super busy because of having a newborn or if she is having a harder time telling me because we did just have a baby. We actually found out that we were one day apart in our pregnancies and it was so hard for her because we both really wanted to be pregnant at the same time. And now she's dealing with this situation and has even less of a chance with one less tube. I know how hard it was for me to lose my pregnancies but I do NOT want to compare mine to hers. That was the worst for me is when someone said "I know how you feel". That never made anything better. Any thoughts?
