5 day old baby having trouble bringing up wind?

My daughter is 5 days old today and we've been having trouble getting her to burp.. We have tried sitting her up, over the shoulder, laying her across our laps and all of those positions and she just won't burp. She's not old enough for any wind drops and things like that so I'm really not sure what to do :( advice please! Hate seeing so upset and struggling with her bottles .
