Hello, and I hope I can help you today.
The most likely explanation for the bumps in your anal area that you have noticed recently, is the development of external hemorrhoids. Hemorrhoids are veins in and around the anus that become dilated from the pressure of your
uterus and the baby's head pushing downwards, especially when you try to move your bowels. The white bumps that you see are most likely hemorrhoids that have not become swollen with blood. The blue one that you see, more likely is closer to the surface, where the blood can be visible through the wall of the vein.
As long as your anus does not itch, or that you don't have any bleeding from the area, there is nothing danger about hemorrhoids. They will generally resolve after delivery.
I would ask your obstetrician to take a look at them the next time you have an appointment. In the meantime, taking sitz baths, which is soaking your rear end in a warm top filled with about 6 inches of water for 20 to 30 minutes, can decrease the swelling.
I hope I was able to adequately answer your question today, and that my advice was helpful. Best wishes for the rest of the
pregnancy, and I hope you feel better,
Dr. Brown
