12 weeks anxiety

I guess I’m just here to vent. I’ve had 2 mc in the past and have 2 healthy living children. 12 weeks today and I’ve gotten my Natera results back. Everything is low risk and nothing at all has led me to believe this is not a healthy viable pregnancy. We are supposed to have a gender reveal today, tell our children etc., and I’m just getting nervous about it. I haven’t had an US since 8.5 weeks and I just hope all is well in there. I did try the at home Doppler a few times and couldn’t find the HB. Deeply regret doing that as I know it’s early.
