Silently waiting for my body to recognize my baby has passed

I’ve helped woman with this. I have had a miscarriage before. The difference with now is we heard our Tiny’s heartbeat at 7 weeks, Tiny’s growth was perfect, and with the other I began cramping and bleeding heavily before my first scan and was at about 5w along. I’m suppose to be 9 weeks and yesterday at another ultrasound....there was no heartbeat and measured 7w6d 😥. So here I am curled up in my bed alone, with my hubs and other kids at their Christmas concert, missing it because I’m really starting to be affected by this immensely. I am waiting for my body to recognize that the fetus is not alive. The placenta is still working because I still have pregnancy symptoms. It’s a very horrible thought to know that I am carrying our dead child, and there’s nothing I can do about it. I know many woman have gone through this, I am just so so sad and not sure how well I am going to emotionally manage what is inevitable passing a tiny baby in the toilet. I know about the D&C and would like to avoid if possible unless absolutely necessary. I am so incredibly sad and the holidays are not making it any easier.
