Very anxious for my first appointment 🥴

This will be my first official appointment since i was confirmed pregnant at 5 1/2 weeks. Then it was jus an embryonic sack and yolk. I’m now 9w6d. 10 weeks on Saturday && My appointment is on Wednesday where i will be 10w4d ... I’ve had anxiety this whole time and sometimes i wonder if I’m imagining things and I’m not even pregnant and my period is just late and I’ve had some bad shrimp 🙃 .. i think its because when they took the first sonogram they said there was “no baby yet”. But apparently that means the signs of the yolk exc were showing it’s a baby just to small to be seen. I’m jus overwhelmed with anxiety and i can’t wait to hear the heart beat. My symptoms have been on full throttle since my initial appointment. Nausea everyday almost all day and sore boobs and tiredness and vivid dreams and food aversions && a stuffy nose. I feel like I’ve lost so much weight. I’ve had no spotting and no cramping. Just the occasional stomach ache from food when i do eat. I keep dreaming about multiples and it’s making me nervous. Idk how to calm myself down but I’m beyond ready for this appointment. I just NEED to see that everything is ok. That they are developing well and their heart is strong !! I have no real belly at least i think so. I was extremely flat before. So i feel like I’m not going to show for another few months. But for almost 10 weeks. With my first, i feel like there’s something there and I’m not bloating. Stomach is firm. All my symptoms have been worse then my other pregnant friends so If it’s two in there I’m going to faint. ( sorry my pants were to tight i guess that’s what that line is)
