its normal, no worries. as longest it doesn't change in color.
Also Another red flag to see a dr is itchy down there, pain or burning when you pee and/or a foul smell
I agree with the other ladies; totally normal. The discharge you need to worry about is green, black, brown or blood-tinged. Most women wear pads during pregnancy because it can become quite messy because there is so much at times.
White discharge during pregnancy is normal. As far as the yellow discharge is pale there is no problem, in case its dark yellow, kindly consult your doc.
Are you pregnant? It is normal to to have an increase in discharge during pregnancy. It is also normal to have this increase in discharge before your period. In pregnany the discharge is referred to as leukorrhea. As long as there is no unpleasant odor you should be fine.
