should I say something?

My cousin and I got pregnant and were due the exact same day! Unfortunately she lost her little one at 13 weeks and I am currently 27 weeks. She just received my baby shower invitation and I feel horrible that she is hurting  (she posted something on Facebook about it) I feel bad especially because me and my husband tried for two years before getting this little one so I know how hard it is to see other people pregnant while you aren't. Should I say something to her or what?
