Hello dear, I understand your concern. In my opinion the bleeding during passing motion suggests the bleeding is from rectum. It might be due to anal fissure or piles. It needs physical examination for accurate diagnosis. Passing hard stools or constipation will provoke fissure or piles. And constipation is a common complaint faced during pregnancy. But nothing to worry as it will subside with treatment. Take adequate fluids upto 3 litres per day,high fibre diet and laxatives to prevent constipation. Once the constipation is treated the bleeding subsides spontaneously. But kindly consult doctor to check for any piles. Topical ointment can be applied to decrease the pain. Also take iron rich diet and iron supplements to combat anaemia caused due to blood loss. Sometimes iron supplements also cause constipation so check if they are the culprit and in that case the preparation need to be changed. Relax.Avoid stress. Hope this helps.
