Missed Miscarriage

Hi mommies, I had my ultrasound last monday for my 10weeks pregnancy. The result revealed that my baby growing at 7weeks and no fetal heartbeat. I suffered a missed ( or silent) miscarriage where my baby dies but sadly my body keep on releasing hcg hormon that still make me carrying pregnancy symptoms. I were told to wait for another 2 weeks for my body to figure things out, for me to start bleeding naturally. I choose to wait coz im afraid of D&C procedure. Saya cuba untuk positive tapi kekadang air mata mcm musim tengkujuh pulak. Menunggu saat bleeding dan cramping rasa lama sangat. Sampai sekarang masih belum ada tanda2 spotting. How long should i wait or should i go for D&C?
