Low lying placenta.

Li
Today my doctor told me some not so good news. I'm super worried about this issue. Does anything had that and it went up? Is there anything that I can do to help my placenta to go up? Or not get lower? Please help. I'm at my 16 week going to 17 weeks.  I got devastated when I read more about it. I just don't want it to get worst or have complications for my baby girl.   😞
