Hi
I will answer your questions one by one.Since you have a history of frequent abortions,the cause should be identified and managed.
Genetic causes, immunologic causes, autoimmune diseases, uterine anomalies, infectious causes, smoking, endocrine factors such as
diabetes mellitus and hematologic disorders are some of the causes of recurrent abortions and must be ruled out.
Ultrasound testing does not produce radiation which harms your baby.Hence do not worry about ultrasound scan being the cause of abortion.
I would suggest you to undergo
fertility investigations to determine any
hormonal imbalance.
Consider taking
folic acid supplements routinely to prevent fetal defects.Folic acid is a very safe drug.
Your TSH levels are normal and you can repeat the tests after 6 months if required.Right now,I would suggest to keep your BP under control since
hypertension can complicate pregnancy.Avoid stress.
Hope I have answered your query. Let me know if I can assist you further.
