For me it was worse, but I was induced using a really high dose of syntocinin. My waters had broken prematurely and DS was still very high. The contractions were incredibly strong and relentless.
Second time I went into labour naturally and it was much more like what I thought labour would be like. It was uncomfortable but manageable as I had gaps between contractions.
It’s such an individual experience. I have a friend who described it like moderate period pain and then others who have said it was much more painful than they had expected.
If I were to say anything to a first timer it would be to go in with an idea of your best case scenario but be flexible when it comes to pain relief. If you need it you need it. Likewise you may be fine with just gas and air or nothing!
