Freaking out a little

Amanda
Yesterday and almost all week our baby was moving a TON. Like almost all day long. Today she hasn't really moved yet and I normally feel her by now. I did feel her a a few min this morning when I woke up but other than that, that's it. I'm getting nervous especially because we had a miscarriage. I'm 21 weeks and wondering if it's normal for her to not move as much one day.
