Bleeding at any stage of pregnancy is dangerous to both the baby and the mother. Early presentation is very important to limit blood loss which could place both the mother and the baby in danger.
The older the pregnancy, the more significant any bleeding episode is; and the earlier the woman presents, the better for her and her baby.
The woman should lie down on her left side with slight head-down tilt. This position reduces blood flow to the lower part of the body and therefore reduces the rate of blood loss before getting to the hospital, while ensuring that vital body organs (brain, heart and lungs) are supplied with blood.
Bringing a bleeding pregnant woman to the hospital sitting down is not good enough as this encourages large quantity of blood loss on transit.
