<human>: Hello doctor, I am 22 weeks pregnant and have some concerns: 1] Can sonography every month cause any harm to my baby? 2] My father in law had fits when he was a child although with time it was supressed, my husband and I am perfectly healthy and so are my parents and my mother in law. Should I be concerned of any birth defect for my baby? Thanks for your reply in advance.
<bot>: Hi, No sonography every month will not cause harm to the baby especially after the 5th month. Initially there were a few concerns that repeated sonography in first few months can affect, but no substantial scientific evidence has come to show that it can affect. So it is safe, but not advised unless there is an indication for it. Since both you and your partner are fine, it is very unlikely that your baby will have any birth defects, especially if the 20-week scan has been normal. Hope this helps. Regards.
