question what does NST mean?

Karen • Can't wait to meet my Baby girl
I'm a FTP I'll be 36 weeks next weeks seems likey Obgyn doesn't tell me anything 😩😩 I DNT even know how many pounds my baby is last I heard I was measuring behind my due date so she has changed my due date 3x first it was Feb 14 then the 11th now it's if I haven't had my Lil girl by the 17th I have to get induced which is not my plan at all because I will have to deliver at a hospital I refuse to go to due to them always rushing the process nd giving 85% of the women who go there a c-section
