Extreme period pain no period

[Purplerainpurplesky]

For over 5 days I have had the most extreme period type pain in my back sides and belly.
Feels almost like contractions, constant for 5 days, no period or sign of period.
It is so bad paracetamol and hot water bottles aren't even touching the sides.
I have had irregular periods for over 6 years but never this sort of debilitating pain.
Should I go to the GP or is it a waste of time with period type pain?

How are you doing, OP?

Any updates, @Purplerainpurplesky ? I really hope you managed to get the care you needed!

Hope you've been seen to!
