My vagina hairs are curly but how can i prevent from getting acne/bumps after shaving , is there something i can use ? or do ?

Not especially : There is not any good treatment to prevent shave bumps in the area. Except electrolysis, which is expensive.

Review with your doc: You are on many meds for a young person and I would caution you about shaving the vagina. The bikini line area is the area that is safer to shave and to avoid secondary acne, abscesses or folliculitis you may want to wash with betadine soap you could buy at the drugstore. With a vaginal bacterial infection discuss avoiding more problems with your doctor. Be well.
