What do it means when you wipe yourself and it's like brown yeast i'm currently taking clindamycin can that cause it and can you get trichomonas t?

Probably not yeast: Presumably you mean brown vaginal discharge, not anal. Clindamycin could trigger a vaginal yeast infection, but yeast usually causes only a little white discharge or none at all; the main symptom is irritation and itching. Trichomonas can cause brown discharge, but is an STD; you only catch it from sex partners. See doctor, get tested for vaginal infections and STDs.
