Not sure how to help

I have a friend (not super close, but good) who had a mc this weekend. She was around 11 weeks. I know they've been trying and it just hasn't happened for them. I'm currently 13+weeks and thanks to my so everyone knew about us since very early on. I've also had 2 Mcs in the past. But we weren't trying this time. I feel like I want to be there to comfort her but since our dates were so close I can't help but feel I won't help and she may just look at me with jealousy or it would be too hard on her emotions. I know if places were switched I would have a hard time going to see her. I'm just not sure what to do. Should I just wait till we happen to see each other? (This happens at least weekly) I just don't know.
