IMO I would try to get them cleared up before you give birth.

When I was pushing, my 'roids hurt more than pushing my DS out! My OB said he had never seen them so bad in a first time mum. I had to have ultrasound on them whilst I was in hossy. My tear caused me no pain, but my bottom was unbearable.

Note to self - lesson learnt for when I have second baby, keep on top of bowel habits!

I also wanted to add that I physically could not drink any more water, or consume any more Metamucil, Benefibre, etc. My colorectal surgeon said that some people have a pre-disposition to poor bowel habits, and that it is usually worse in women than in men.

Good luck.
