Will be brief as on a quick break at work. I never used to get much in the way of period pain, but in the past few months the pain has become shocking - nausea and what I can only describe as labour-like pain, except with the brief respite between contractions that you get in labour. I've been bent double with it. Last month this was on day one of the period, starting before bleeding, this month it's been day three. My cycle has also shortened to 25-26 days at the same time. Am 39. Has anyone had experience of this? I have booked a routine GP appointment for a week's time but would be keen to hear people experiences nonetheless.
