heart broken 💔

So I had some spotting Wednesday, pinky brown. Turned dark brown Thursday and light browny cream this morning. I decided to go for an early scan today just to make sure. I'm 9 weeks and 1 day but pregnancy is only measuring 6 weeks. My dates definitely aren't wrong so our little jelly bean is gone 😢 devastated. I was told to get another scan in about 10 days just to confirm. 
I don't know what happens now, I'm terrified of what to expect from a miscarriage, the nurse just told me it will be like a heavy period but if it's extremely heavy and I'm feeling faint to go to the hospital. I'm so scared 🙁
This is my second pregnancy. We have a healthy 20 month old boy 💙
