Pregnancy after MC : TW

I have two beautiful children that I had back to back in 2016 and 2017. In 2020 (May), I experienced my first MC (a blighted ovum). I found out Christmas that i am pregnant again. My periods have been so weird since MC so no clue how far along I am. I think my last period was early November or late October. I have an appointment for blood work Wed but can’t get an ultrasound until the 6th. I’m absolutely freaking out. I’m convinced it’s another MC. How do I get past these fears? My pregnancy test line was very dark and bold- and after me drinking lots of water- so I’m hoping that is a good sign because it def wasn’t this prominent with my MC. Although I know that could mean absolutely nothing. Has anyone had a MC and then a healthy pregnancy soon after? Thanks for your support. ❤️
