Hello, During pregnancy, there is increased vascular supply to the skin and pelvic parts. There is also increased pelvic pressure owing to the enlarging uterus. Together, these can cause varices of the rectum and anal canal which may bleed on pressure while defecation. Infections of the bowel also can lead to such symptoms. You can see a surgeon for a local careful examination to rule out any external or internal hemorrhoids and fissures. Adequate bed rest, diet regulations to make the stool softer and avoiding constipation are the mainstay of management at this stage. Local applications can be used to heal. Hope this helps.
