I had Asher on a tuesday evening and had my first poo on the saturday morning, so that's just over 3 days.
I was really worried about it as I was pushing in birth for over 2 hours and had really quite damaged the whole area.
I was prescribed laxative tablets from the hospital as I was also on codeine (which constipates you).
I just sat there and let it come. My mum had had horrible problems pooing after birth as she had been so scared that she held it in, and then it wouldn't come out. So I knew I had to go otherwise it would have been worse.
It was absolutely fine, didn't hurt or anything. Took a little while, but you can't rush or push too much after giving birth anyway.
I did get horribly constipated a few weeks later though (was on iron tablets), and had a very unpleasant incident, which I won't go into now.
I agree with Leckershell though, when I need to go now, I really need to go!
