changed due date

so we go to the hospital tonight for contractions and stabbing feelings in my vagina (nothing escalated 3cm dilated so ended up coming home) BUT while we were there I find out they changed my due date and didn't even tell me!!! the nurse goes so you're due today? And I'm like no I was due five days ago, after the doctor came in he tells me my ob had changed the date and did this months ago 😲😲😲 I have been losing my mind for the past week thinking I've been over due and this boy has been on track this entire time 😧
