Hi Dr. Purushottam welcomes you to HCM virtual clinic! Thanks for consulting at my virtual clinic. I have carefully gone through your case, and I think I have understood your concern. I will try to address your medical concerns and would suggest you the best of the available treatment options. Livogen - is a iron supplement. Usually it is advisable to take it after 14 weeks of pregnancy. The symptoms that you are narrating are known after iron tablets. I usually suggest to take iron tablet 30 minutes before or 2 hours after meals. This eliminates tummy problems in most of the cases. If you still find intolerance to oral iron,doctors can opt for injectable iron. Please remember, your symptoms are not going to cause any harm to baby. I hope my answer helps you. Thanks. Wish you great health.
