White vaginal discharge, also known as leukorrhea, is very commonly noticed by expectant mothers throughout pregnancy and is usually nothing to worry about. Leukorrhea is odorless or slightly odorous.
What is the reason of this?
Most women notice white discharge before pregnancy, the only difference is the fluid level in the body. Pregnant women have much more blood and water in their systems than non-pregnant women, meaning pregnant women are more likely to discharge white fluid.
Tips
There is no way to stop leukemia and you should always avoid tampons while pregnant, but using thin pads can help control the discharge. If your discharge is green, yellow, or blood-colored, or has significant changes in consistency or odor, you should probably call your healthcare provider to make sure everything is OK.
