TMI warning. Please help

Alayna
So, I saw an old post on here of a girl who had the same exact thing and I commented on her post to see what it was, because she said she was going to get it checked out, but I haven't gotten a reply to my comment. But I just discovered this vaginal discharge that appears to be really white and creamy. And it smells like vomit or baby vomit.. Any ideas?
