Didnt smell bad! The room had just been cleaned when I went in so there was an odour of milton (typical hospital smell) and when my waters went it smelt sweet. There was a slight odour of blood but no way unpleasant.
To be quite honest, smell is the least of the worries when you are pushing a baby out of your vagina with crippling contractions! I think during pushing I shouted "I don't want to poo myself!" and that was the main thought at the time, but not once did I think "wow, I wish someone would Febreze the room"
