After miscarriage, what next?

It was confirmed that my baby died last week. I loved that baby so hard but something felt off. I didn’t know that it happened, not logically at least but instinctively I felt it. I prayed so much I was terrified to even go to the bathroom or move the wrong way, I had a dream about it and the first thing I thought when I woke up is “God has my baby” I tried to take it back but I knew. Still hit me like a ton of bricks when the doctor said they couldn’t find a heartbeat. I so desperately wanted to be wrong. Logically, I know things happen and I didn’t do anything wrong but part of me feels like I somehow manifested it. If I hadn’t been so scared or if I talked to my doctor sooner… if, if, if. I don’t know how to talk to anyone about this but I know a lot of ladies have been through similar experiences. I could use some prayers, advice, anything you have to give. I don’t know how to move forward without constant fear. I don’t know how to be excited about the possibility of it happening again and trusting that my body will do what it needs to. They tell you what to do with your body after it happens but my heart hurts and my head is a mess. Where do you go from here?
