advice pls !

Catherine
so tomorrow i have a follow up ultrasound and im so nervous, i went a week ago exactly for my first prenatal appointment and they did an ultrasound to make sure all is well because of a missed miscarriage i had back in august of last year and i was also having a little yellow and brown discharge which turned out to be a yeast infection, my doctor confirmed it yesterday...everything was great on the ultrasound, the baby wad measuring 6weeks 4days with a heartbeat of 133 !!! so now i have to go back tomorrow to make sure everything is on track and i cant help but to be super nervous, and my fiance is coming with me, this will be the first ultrasound he goes too, which makes me even more nervous !!! i just want everything to turn out great, and i keep telling myself that, but its hard because im always so hard on myself and im also completely paranoid because of my past experience !!! any advice ladies ?!?
