I think this is my rainbow baby!

I had my first miscarriage about 2 months ago. I was 8 weeks at my first ultrasound when they told me there was no baby only a sac that stopped growing at 6 weeks. This is our first cycle trying again! I’m only 10 dpo, this is really real right?? I’m so scared to get too happy I don’t want anything bad to happy to this baby..
