Food Questions

Kymberli • Me and DB have been together for 5 years and this will be our baby #1&2❤
9 weeks 5 days pregnant with twins and I need to know can I eat Tuna? What about ice cream, because I read on the container it contains propylene glycol which in lamens I understand is antifreeze??? Uggh the internet is so conflicting on this so any help would be great!
