Had a chest Ct with contrast and had lower back x ray in the within the last two years and feel so worried about my radiation exposure from these. Feel the tests weren't really necessary and both times doctors just being cautious, but as i've been so anxious i had tests done anyway. now I regret having them done. Have a baby under 1 and feel so stupid and guilty as fear I May have now increased my chance of problems down the line. I worry more as im in my early 30's, slim, female and odds are bigger for any effect from the radiation. If anyone could offer advice, i'd be grateful
