Fiancé freaking out! Trigger warning

So not that long ago he learned his cousin and his girlfriend were also expecting a baby! The baby was due 3rd week of December!

Well.. two weeks ago we learned that his cousins baby was stillborn 3 weeks before full term! We reached out to the family and have given them as much support as possible! I stayed away and only called because they voiced that they would rather not have me around because of my pregnancy!

Well now my fiancé is terrified that I might loose our baby! He is over protective and now is acting like I'm extremely fragile! I can't do anything myself, he is constantly asking if I've drank my water (he wants me to drink more than doc recommends!) and constantly asks if I'm hungry and if I say yes it's fruits and veggies! Like no I want to snack on my pizza rolls or mac n' cheese! I haven't had any sugary anything since he heard about his cousin! I can't have anything that's not "super healthy" either!

Help??

Has anyone had to reassure their SO?

I really just want some macaroni and cheese
