Panicking!

Somebody who can help ease my panic. I’m currently waiting for my ultrasound which will be by the end of this week. Will be 8 weeks then. I’ve had zero symptoms. Just slight tender breasts early on and some nausea occasionally. Not where I would actually throw up. I read somewhere that your water can break even if you’re asleep during a MMC. Now I can’t fall asleep either fearing that something might happen. Anybody who’s currently 8 weeks pregnant and equally anxious, who can help me out here
