Gut feeling????

I pray that I'm wrong. But I feel like I lost the baby in what's consider a missed miscarriage. I'm going to the doctors to double check, but it hurts me thinking it can be true. I have no cramps or bleeding. I will be 12 weeks tomorrow and I just don't feel pregnant. My body doesn't even look pregnant. I just hope it's all in my mind and baby is ok. It's aweful feeling thinking something is wrong with with your baby ??
