Nyasha, if I get this question right, you want to know what the symptoms of pregnancy are and specifically if whitish discharge is part of the symptoms.

There are lots of signs and symptoms associated with pregnancy and these varies with individuals.
The common and general ones are nausea and vomiting, breast tenderness, increased frequency of urination, fatigue, food cravings and aversions , heartburn, bloatedness et al.

Among the symptoms is the vaginal discharge which could range from white to milky and slightly yellowish in color. They are as a result of the pregnancy hormones circulating your body.

If uou don't feel comfortable with it (there's actually nothing you can do ?) you can regularly wash up and or use a light sanitary pad to help absorb the discharges.

Be fine, I wish you a safe pregnancy and delivery.
