Freaking out

Kristeena
So I had a miscarriage in August and had one cycle and got pregnant in October. I am currently almost 10 weeks pregnant. I am freaking out bc I have been having cramping for the last two days. I scheduled an appointment with my doctor for tomorrow. I have no bleeding or spotting. I may be a bit paranoid because of the previous miscarriage. I had no bleeding then as well. They say the baby was only measuring 9 weeks and had no heart beat. That's why I'm freaking out. Has anyone has cramping during the first trimester. It's closer to my pelvic bone and runs around to my back area. Any advice would be great!
