This seems like the group I need

Hey guys. I had a miscarriage on Jan 7th. I did get a negative pregnancy test. Today I felt for my cervix. It’s very high almost unreachable. I’m extremely constipated and have horrific heartburn. I’ve been having some random spotting. Is pregnancy possible or probably unlikely? If I am it’s probably too early for a positive test. I had some thicker mucus with brown tinge in it that I was considering to be implantation a few days ago but I’m not sure if maybe I’m just convincing myself because I really wanted our baby.
