Is it normal that discharge during pregnancy has unpleasant odor?

Preg. discharge: If not accompanied by itching, pain or other symptoms suggestive of infection.

Maybe: As many shifts happen in the body during pregnancy it is common for vaginal secretions to change consistency and odor. However, some discharges can be signs of problems such as infection. Unpleasant is a subjective term, so hard to interpret. If pain, discomfort, bleeding, etc exist, please be checked out!
