I feel like something's not okay

I'm not sure why but I just have a feeling like "what if she's not okay". I haven't been able to go to the doctor yet due to insurance issues so I haven't had a check up on my baby yet. In 14 weeks. I feel like I'm still growing but there's still a pit in my chest like the heart beat may not be there and I don't know why. Early in my pregnancy I had a brownish discharge and it's happened two times since once was last week. I want to go to the doctor and just ask them to look for a heartbeat but I don't know if I can do that or not. I want my baby and I'm really nervous about this. I still have my symptoms my nausea has passed for the most part but maybe that's just because I'm in my second trimester but I'm still having headaches and fatigue. And here's a photo of my stomach. Please anyone tell me what you think !
