Yellow pee in the morning, is it a cause of concern!?

Hey mama, First off, congratulations. It’s normal for you to be dehydrated first thing in the morning and therefore the colour of your pee - despite you drinking lots before heading off to bed. Do note that your body needs a lot more water now - the amniotic fluid for baby alone contains mostly water :) The increase in certain hormone levels can also cause this to happen.
