period pain?!?!?!?!

I had one laaargeeeeee period pain that lasted 40-50 seconds with some pelvic pressure it was really painful, it's stopped (the period pain)... came at 1.12am(U.K. Time) and I've had a mild period pain only just not for long... this isn't labour is it? :( I'm 40+2 😢 my waters haven't broke nor have I lost any plug :( or am I just wishful thinking ?
