Sinus spray safe to use during pregnancy?

I’m seeing ENT clinic and has been on avamys for years. They stopped the spray immediately when I said I’m pregnant. They gave me sea salt spray to wash instead. Seen a few gynaes and some said ask to check back with ENT dr. ENT dr said I don’t specialise in pregnancy 😅 End up I started using at week 21 on alt day. My gynae did ultimately give the green light. But I’m concerned about the steroids. So try to reduce usage of spray. Can’t stop totally because can’t stand the blockage 😂
