I'm not very impressed with the posters mocking women for screaming at 2cm. Every labour is different, some are more painful than others, some are longer than others, some don't progress... why the snarky comments?
Yes, I've been reading through this thread and those comments are really unkind. Before I had a baby I thought the really screamy women on OBEM were being ridiculous. I'd been to NCT classes and was sure that I would have a drug free birth. But when my contractions got so bad I was sure the baby was about to arrive any moment, it turned out I was only about 2 or 3 cms dilated and this agony continued for hours and hours without dilating much further. I ended up needing every type of pain relief the NHS has to offer.
So yeah, everyone really is totally different. I don't even think it's always about subjective pain thresholds either, we are all physiologically different too. I had a smear test over a year later and the nurse noted that my cervix was still raw from the birth, which confirmed my suspicion that internally something went wrong!
