My first transvaginal ultrasound since..

so I just found out I'm pregnant yesterday and after a lot of work I got the Dr to take me in today to do an ultrasound and blood testing as a preventative measure for having another MC. I don't want to have to go through that twice. I found out I was miscarrying at my first transvaginal ultrasound at 7 weeks +2 the first time. I'm so scared I will look at that ultrasound screen and see nothing again, I'm six weeks +5. I'm freaking out, literally on the verge of tears. we are on the way there now. Need thoughts and well wishes...
