hi, I think it's better for you to get your piles treated right away, due to your pregnancy. I recommend visiting Dr. Dennis Koh at Colorectal Practice. He successfully treated my piles in the past, and I can attest to his surgical skill and precision throughout my treatment.
If your piles are already making you miserable, I highly suggest seeking a doctor who specializes in treating this condition, instead of your personal gynae. I highly recommend Dennis Koh of Colorectal Practice. They will provide treatment according to the severity of your piles.
