Hi Dr. Purushottam welcomes you to HCM virtual clinic. I have gone through your query. I think I have understood your concern, I will try to suggest you the best possible treatment options. 1] As such there is no data telling hazards of infection on fetus as such. But it may lead to anemia in the mother. 2]Also data suggests, that hardly there are any other treatment options that are safe till 14 weeks of pregnancy. 3] I will suggest to use probiotic Saccharomyces boulardii available as sachets or capsules and Cap Vibact DS , these are helpful microbes in the gut. 4] have good filtered water, healthy and easily digestible food. I hope my answer helps you. Thanks.
