Hi there. Yay, pregnant and 22 weeks! How are you feeling? I'm sorry you had an ultrasound that came back with "something is abnormal". But this situation I do know is told to a lot of women and it turns out to be just fine. It fixes on it's own. Hard not to worry but think it will be fine! What did your doctor say or did just the ultrasound tech tell you?
Hello and welcome to MedHelp's forums. Congratulations on your pregnancy. It is always scary when you hear something outside of normal is going on with your growing baby. In this case, what you are being told is very common in fetuses and typically resolves on its own. https://radiopaedia.org/articles/fetal-pyelectasis. Please talk to your doctor about this but this should be the case with your baby as well. Again, congratulations.
