Idk what to do at this point

Why do I do this to myself.. I'm 11 weeks 2 days no indication that anything is going wrong but my brain is convincing me that it's not okay and everything's going wrong. The top test is testing out the hook effect(dilute urine with equal parts water And yes I measured it by the milliliters cause I'm not ok) you can see where it's a stronger dye stealer than the one on the bottom so I know by testing everything's great. But my brain constantly convinces itself that it's not okay and everything's going wrong and I can't even enjoy my hobbies I can't enjoy life right now and even after my ultrasound next week I probably still won't be okay I might be for a day or two but then this anxiety is going to set right back in. And I don't know what to do I don't know how to make it better. I have a Doppler that I use weekly but I haven't heard a heartbeat at probably because I'm a bit bigger of a person so that's not exactly bringing me any comfort even as I tell myself you know A) early and B. you're bigger so it might take a little while longer to hear. I just don't know what to do to stop being so obsessive over testing and stressing out every moment. This is more of a vent than any specific question but I just feel so alone because no one in my family is going through this until you go back to my great-grandmother's no one's lost a baby No one's been through that pain so I feel really alone.
