Don't feel pregnant anymore

I'm 8+3 and just don't feel pregnant anymore. I had morning sickness pretty bad for a few weeks but haven't been sick in 3 days. My boobs aren't really sore anymore and I'm less tired. I had a mmc a few months ago and I'm just so scared it's going to happen again. I try to talk to my husband about it but he's so sick of hearing me worry and will just say "you're fine. Stop worrying." It's really not that easy and I wish he knew how I felt. It's so stressful. I wish I just knew if my baby was okay.
