@Wanyu you had more than one before the transfer? Was it days before? Or a week before?
I had intralipids 2-3 days before my FET. My FET was successful but then I suffered a miscarriage in my 7th week.
I think it was one before the transfer and then 2-3 times after. Can’t really remember the exact timing though. I’d say trust your clinic!
Can’t really remember but I had it a few times, before and after FET until pregnancy was stable. They also gave me steroids so I can’t tell which one helped. This is after 3 early miscarriages.
