First time anxieties 😕

Just made it to 10 weeks yesterday. I've been super sick most of the week for the last 3 weeks, but I woke up yesterday and feel 100 times better. I don't have my first OB appt until the 29th and won't have another ultrasound until at least the end of august for gender. I'm having extreme anxiety about feeling good...like, I'm worried something happened to Bean. I'm trying not to stress but I can't help it. It's so tough not being able to know what's going on, being blind in a sense. Last ultrasound was @ 9 and a half weeks, baby looked good, heart rate was 173 BPM, I've had no bleeding or cramping or anything. Everything points to Bean being okau, but like I said..I just can't help but worry.
