Sayang, this is really something you should confirm with your doctor first, they know your specific situation best and can assess whether it's actually needed A few of us mum friends have had different scans during pregnancy, but MRI for the brain is quite specific, so do chat with your OB about it. They'll explain the safety info and whether there are other options first. Don't worry too much, just get professional advice so you can feel confident about whatever decision you make! Hope everything's okay with you
