I started my cycles 7 WEEKS after having my DC
Took me by surprise as I'm exclusively breastfeeding.
I'm now 6 months post birth, I've had about 4/5 regular cycles since and the pain in between them is horrendous.
The periods themselves are very very light, so I can't say I've had any deep bleeds or clotting.
I cannot sit up straight at certain times, but funnily enough, the period itself is the least painful thing.
It's after and building up to it that's bad.
I've never had painful periods before, ever.
Will GP do anything for me or laugh me away? 
I've tried strong pain killers and they don't touch it. The pain is like contracting with my labour pains all over again, except maybe worse.
