worried

Today I really don't feel any symptoms besides having adversions still. Last night my boobs felt like the hurt really bad and nipples were sensitive and that was the first time they felt like now now they're fine. They don't even hurt when you press on them. I'm at a very high risk of miscarriage because my babys heartrate is really low. And I've read once you stop feeling symtpoms that's pretty what you think is going to happen. I really hate thinking this way, and I'm so scared to lose my baby, but I just know my risks and it's not good.
