paranoid about miscarriage

H • United Kingdom❤️. TTC1 Long term relationship: Daryl❣.
Hello ladies ☺️ 
I'm 10 weeks pregnant with my first baby. 12 weeks ago I had a miscarriage I was 7 weeks gone, I no I got pregnant quite quick but that's life 😊
I've had two scans and midwifes were very happy with my baby
But I'm absolutely terrified that I'll have another miscarriage I haven't had much morning sickness but my boobs and back are very sore. I read online that you can miscarry without bleeding which probably doesn't help me knowing. Am I been  stupid for over thinking? How can I put my mind at ease
