More blood to kidney
, even as early as the first month, your blood vessels dilate and blood volume increases.
This causes more blood flow to your kidneys, which creates more urine
, so you'll need to go more often. As your uterus
grows, it will press on your bladder
also. If you are experiencing any burning or pain during urination
, see your doctor as you may have a urinary tract infection.
