Multiple ct scan. Me cancer in future?

Hi iam 27 years old female.I have some queries related to repeated ct scan and x rays .In 2017 I had ecg twice and 2 d echo once as I was having chest pain and due to my ocd and doubts I underwent it.then I had breast scan in 2018.chest X-ray in 2018 and thrice head ct scan in 2018 (2 head ct scans within period of 2 weeks).Also I had throat or neck scan in 2018 .again chest X-ray in 2019 and recently in 2020 had chest ct scan .All due to my ocd.now I am worried if this much exposure to radiations will cause me cancer in future?my queries are 1) as only 1 msv per year is safe I have undergone three head ct scan within a year and head ct scan will be 2 msv which is more than safe percentage so will this cause any cause as I took three ct scan of head in a year in which 2 ct scan were within 2 weeks period. 2) also along with these breast throat scans and chest X-rays also so this much of radiation will it cause me cancer plz repl iam very much worried.
