Rainbow baby anxiety

My husband and I are trying for baby number 3. Got our first positive the day before christmas 2018! We were so excited. Then 1/5 I started lightly spotting and 1/6 its was full on bleeding. I miscarried. My levels were back to negative 1/14. I got a faint positive hcg test yesterday at 9dpo and I have so much anxiety that it will happen again. I find myself testing multiple times a day, knowing it is ridiculous. Any success stories of getting pregnant right after a miscarriage??
