HELP !

Bianca

so I went to the doctor about a little over 2 weeks ago & I was “5 Weeks” (First Picture). Went Back today & I’m suppose to be 8 weeks but measuring 6.... (second picture) anybody else have this problem & everything turn out okay ?! All my doctor keeps saying is “it’s a miscarriage” because he couldn’t detect a heartbeat...I have no bleeding or cramps & still feel very pregnant . Need some hope.
