The wait is killing me!!!

Anyone else who is pregnant with their rainbow baby having such a hard time waiting for the first appointment??? We had a missed miscarriage at 9 week in January after seeing he heartbeat at 7 weeks which was the most devastating times of our lives. I have a good feeling about this one but my paranoid mind worries sooo much. What if it's ectopic? What if it's another missed miscarriage? My first appointment/ultrasound is on the 26th when I will be about 8 weeks. And it seems like aooooo far away. I just keep praying we hear that heartbeat and that it is in the right place. I try to keep reminding myself not to worry because there is nothing I could do differently to change the outcome. I keep trying to remain as positive as possible becAuse I know any stress I'm feeling is only going to hurt my baby not help! Anyone else struggling with anxieties like this?
