I have vaginal and anal itching during pregnancy causes and treatment?

Yeast?: The most common cause of vaginal/anal itching is women, pregnant or not, is yeast (thrush, candida). Check with the doctor or clinic managing your pregnancy. Probably safe to try an over the counter "azole" vaginal cream or suppository (miconazole, clotimazole, others). All are equally effective -- the least costly is OK. For sure see your doctor if such treatment doesn't help.
