So much anxiety

I found out yesterday I am pregnant - it was an instant positive and very dark line which is encouraging but I can’t help worrying I will miscarry again. I’ve had two miscarriages so far this year, both before 6 weeks. Im reading into every little thing so worried it’s going to happen again. Like maybe my boobs are slightly less sore today. I know worrying won’t do anything and it’s out of my control if it happens again, I just really want this to work 😩
