Vaginal bleeding after birth. It is normal to have bleeding after your babyâs birth, whether your baby was born vaginally or by caesarean. More often the blood loss is heavier after a vaginal birth. An average amount of blood when a women gives birth is between 200-300ml. Your body prepares in pregnancy to lose a significant amount of blood immediately after the birth, with a large increase in the blood volume. Lochia is the name given to postnatal bleeding. Lochia is very similar to the bleeding you experience during your menstrual period; however, it is much heavier. It typically begins in the hours immediately following birth and usually continues for two or three weeks. However, in some women lochia can last for up to six weeks.
