Let me know your opinion!

Okay, so I'll start from the beginning. I found out I was pregnant in September! I was so happy but it was short lived. I lost the baby by the end of September. On October 7th, my HGC was 0. I was told to wait 2 months to try and conceive again, but being as stubborn as I am, I didn't. I got this positive test around October 25th. I'm now currently 6 weeks and 3 days until I go for my US December 30th! I'm so scared and worried everyday that I'm going to miscarry again.. does anyone have any stories after miscarrying? Good or bad please tell me!!
