What does the vagina look like when you have trigamonus?

Trichomonas: Do you mean trichomonas? If so the vagina will look normal. Sometimes people have a bubbly yellow or white discharge and odor but not always.

Strawberry cervix: Classical presentation of trichomonas is called the "strawberry cervix" - the cervix is red and punctated, like a strawberry. The vaginal walls are typically normal, although you may see some discharge as well as, classically, a fishy smell.
