No, it's biologically impossible to menstruate while pregnant.
Menstruation is part of the menstrual cycle, a regular pattern of ovulation and the body preparing for pregnancy, or when there is no pregnancy the uterus lining shedding and the whole process starting again. Thus when pregnant the menstrual cycle is no longer carrying on, no ovulation and no menstruation.
