Thanks everyone for your replies!

Fresia: I've had these pains this bad since my periods started and have coped up until now.
Anna342 I will give that a go and Susan888 I will also give that a try.
I am feeling a little better after some sleep and a nice hot shower, I'm just resting today but will try to go for a light jog this afternoon to help with the pain. Let's hope it does help!

I'll be making sure I eat some nice salads and fruit today, especially avocado. I've heard that can help a lot and is very satisfying to eat when you're in pain! Looks like salmon with a lime and avocado salad for me tonight!

Thanks for the tips guys, I still have some slight pain, but hopefully with exercise it'll ease off a bit.
