Silent miscarriage

Hi wondering how people cope after a missed miscarriage? 

Im not blaming myself or anything like that for my miscarriage but I am annoyed with my body for not having a proper miscarriage and letting me think I was still pregnant for 3 weeks after the embryo stopped developing

i should probably say there's a small chance that my dates are wrong and it could jusst be earlier in the pregnancy than I thought at the ultrasound I was measuring 1.9mm 6w4d but my dates say 9w5d 

got to go back for another scan on 12th Whicknis horribe cuz I really don't want to go for another scan to tell me all over again that my baby died
