12 week scan anxiety

I have my 12 week scan tomorrow and I am so anxious and worried. I just want everything to be okay 😢 we had an early scan at 9 weeks and saw the heartbeat. Everything was great and they told us baby seems healthy and exactly where they need to be. I have no reason to feel worried as such, had no severe pains or bleeding and have been getting a growing bump in the last 2 weeks ❤️ can anyone offer any words of reassurance before tomorrow? Feel like I won’t sleep a wink tonight
