Anyway to know everything's OK?

Krystal • 29 years old. Expecting our 1st on Oct 27th.
I'm almost 12 weeks, and we want to announce publicly at 13, but I don't have another doctors appointment for a couple weeks (when we will find out the gender). I went to doc around 9 weeks and everything was totally fine. Is there anyway to know everything's OK? Haven't had anything abnormal - no bleeding etc. Thanks! 💕💕
