I watched my first ever episode on Sunday night when DH was out. I can't remember what channel it was on though, sorry. Maybe E4 or More4.
I know loads of women love it but please watch with caution if you're in any was nervous. I really wish I hadn't watched it. There was a woman absolutely screaming throughout the entire thing (even when she'd had an epidural), she was in a terrible state and I was sat there horrified and crying my eyes out. I really don't understand how this programme is considered entertainment because it was horrific. I'm now even more scared of child birth then I was before. On the other side of the coin, there was a younger woman who could hear all the screaming and was terrified by it but she did brilliantly. But obviously it's the screaming woman that I've now got stuck in my head.
