Summary of diagnosis of pregnancy

Positive signs of pregnancy are those signs that are definitely confirmed as a pregnancy. They include

- fetal heart sounds,- ultrasound scanning of the embryo as early as 6th

week, - palpation of the entire fetus, - palpation of fetal movements,- x-ray fetal skeleton at 16 week, and actual delivery

of an infant.- Auscultation of FHS
