Endometriosis

I’m 15, last year I was in hospital for at least 4 days with horrible cramps that had crying and doubling over in pain. My gp said she thinks I may have Endo but she said she didn’t want to get me tested unless I went on the pill, I’ve been on the pill for a little bit over a year, I got told to not take the sugar pills because she wanted to know if it would help. I get cramps a fair bit but this time I have had the worst cramps and I’ve had them for 4 days, the first day was painful but the second and third day have had me bedridden and in so much pain. Today is a bit better. I don’t have an appetite, I haven’t eaten for 2 days, and I feel so unwell. Can someone tell me if they have had the same symptoms. I see my gp next week and will be telling her everything
