  1. Primary amenorrhea means that the patient had never have menstruation at all. This only happens in congenital disease, not pregnancy. Pregnant women must have menstruation before pregnancy and then, amenorrhea due to pregnancy which is considered secondary amenorrhea. Thank you so much for your feedback.

  2. Sir here is pregnancy i think I saw it in alot book why here you mentioned Turner syndrome
