My first ultrasound

I have my first ultrasound on October 12, although I’m super excited and so ready to see this little baby... I’m so scared of the first ultrasound. What if the mess something up? What if they tell me it’s an unhealthy pregnancy? What if they say it’s not gonna stay? All these what ifs have me totally consumed and I am so so scared. I haven’t told any family yet so I can’t ask for any advice. My poor boyfriend has no experience or words of advice. I just have so much comfort knowing my little baby is safe inside me and going to the doctor with the possibility that, that might not be the actual case is killing me. I can’t focus on anything else. Am I the only one feeling this way or is anyone else? I really need some advice.
