Thank you Yvonne for asking this interesting question.
It is quite common to have piles problem especially before and after delivery. But there could be other causes for the bleeding as well.
Most of the time, it would improve greatly a month after delivery.
Trying to soften your stools by taking laxatives and more fluids would help as well.
You could see a GP to have it examined to see if your piles require surgery. Most piles do not require surgery to treat.
