Could be it is luck of the draw, as I never got them and I pushed for almost 2 hours!
I think, particularly with your first, that reading some good articles about 2nd stage might be helpful. I thought that the care I'd received during my birth was fantastic, but when I think back to it now, I wish I had've known more about 2nd stage. Mine was heavily coached, I was pushing so hard I literally burst loads of little blood capillaries in my head, and it was all directed pushing, rather than just following my body's lead.
