My periods have been getting worse and becoming hard too cope.

I'm not sure what's wrong, I definitely don't think endometriosis is unlikely but I'm not sure when/if I should try get tested.

I started my period barely before I was 13, wich is late for my family, my mom and sibling both got it at 11. I'm soon to be 16.

So my periods had not cramps at the start, or very mild. By this time last year I was reliant on solpadeine(codeine + paracetamol, one of the strongest over the counter) every time I was on my period and nothing else helped, about moderate cramping.

As the months continued I started missing the end of school for atleast a day every period, and losing sleep was a given, and progressively stopped me from school for 1 or more days every months.

The last 3 months have been terrible for cramps, each period was debilitating cramps putting me on the floor in fetal position with heat pads and pain killers close to tears. I saw the GP between my last period and the one before and I was having debilitating cramps but no where near my period for around a week. It was awful, I couldn't be separated from a hot water bottle.

I've been proscribed ponstan, wich seems to work ok, not perfect but still.

IDK what too do, I'm getting cramps as we speak five days after my period, I dont think I'm even bleeding at thus point. They started mild but are worse as I type. I guess I'll take some ponstan and try to live with it.

Is this all normal? I hate it, I feel like I can't escape period pains and it's awful. I hate being on my period and now it's like it's never over.
