Stressed, nervous venting ig

So I was pregnant earlier in the year for a little bit but I lost it in august fast forward a month I go in since I haven’t gotten a period since loss and I am pregnant again. My first real appointment this time now that I’m almost 3 months. Is ending up to be the ultrasound. ( for the blood work to confirm I didn’t need an appointment just went down to the labs office) Which I’ve never had an ultrasound before so like I’m already nervous but I just keep thinking what if we go and it’s bad news what if there’s no heartbeat or somethings wrong. I literally have only told a couple people cause what if like it’s bad what if they say there’s nothing somehow. (Also only told my mum and siblings cause they were planning my 21st and yea ) I haven’t had any bleeding or anything but I’m still really nervous cause it might not be good news since the last one immediately before this was a miscarriage. Sorry for like boring or wasting anyone’s time with this I’m just really stressed and nervous and feel like I don’t know anyone irl that’s similar or had a loss. I just figured out what the rainbow baby thing even ment like an hour ago
