Fist miscarriage

I just found out for sure that baby stopped growing at 7 weeks and I thought I was 12 weeks. I am sitting here waiting for it to naturally to happen but afraid I will accidentally flush my baby down the drain. The clinic gave us a jar where we can put the remains and take it in where they cremate the remains and they will send it to a cemetery where they have a service in May for all the babies. I really want to do this. I am afraid that I will go pee and miss it. I don't even know what I am trying to ask. They told us about the other options but they sounded so wrong. Like I understand my baby is jo longer with us, I do but they sounded like abortions. I don't know. Sorry everyone. I'm just in loss of what to do.
