Iodine after CT SCAN, how many MG?

Hey all! So I've been on and off taking Lig's solution getting up to 30 mg. I've had to have 3 ct scans in about 3 months. Horrible, I know, but they are looking for a pulmonary embolism. Can I take Lugol's solution after my low dose CT scan? I'm also pregnant (18 weeks) so I'm not sure what dosage I should take, especially after having a cat scan. Help! Tweet
