Worry, thoughts, anyone else?

I wasn’t so bad at the beginning, I was able to pass them off. However, as I get further along the worry seems to get worse! I’m 10 weeks and 3 days, with a scan in exactly two weeks. First pregnancy with no past of any pregnancies or miscarriages. I had a scan at 7 weeks as I had severe pain (turned out to be cysts that went away a week later), and saw a heart beat. However, I still have a MASSIVE worry of miscarrying or being told the heartbeat is no longer there. I feel insane, has anyone else experienced this and can ease my mind to help me sleep at night?

No signs of spotting, general pregnancy symptoms, still severe morning sickness and getting more and more “bloated”, the odd discomfort but not severe cramping.
