I have this...and it hurts

Hydronephrosis Due to Pregnancy...
Problems with the kidneys and ureters--tubes that lead from the kidneys to the bladder--can sometimes lead to Hydronephrosis. Hydronephrosis is a blockage in the kidney that causes the flow of urine to the bladder to be obstructed (also causing kidney stones and urinary tract infections.) Pregnant women have a higher chance of this difficulty as their uterus ENLARGES. Treatments do exist for Hydronephrosis in pregnancy, however, most cases are mild and go away AFTER GIVING BIRTH.

...I hope I can make it til the 31st, wish me luck!
