Miscarriage? No heart beat...

Found out my baby's heart was not beating today at 25 weeks 4 days throu routine gyane appointment. Was sent to hospital to do a second scan to confirm & there is no heart beat. Report says that baby might have stop developing 22-23 weeks & legs are becoming smaller. So i have to wait another day til Monday to pass my gyane the report. Can someone tell me what I should do or expect? I have no bleeding or cramp at all. But 2 weeks ago I felt lik there is less movement. #advicepls #pleasehelp #firstbaby
