Protein too high- due to diet or endometriosis?

Hey everyone! I went in for the first time about a month and a half ago, my protein was 8.3 (they allow 6-9) but I was deferred for 6 weeks due to taking prednisone. I went in today and everything was fine, except my protein read at a 9.8... I drink 1-2L of water daily, however due to finances my diet usually lacks any protein- stuff like kraft dinner, mr noodle, potatoes.

Yesterday one of my friends gave me a chicken pita wrap with lots of veggies and a protein shake, and then this morning she gave me 2 eggs mixed with a slice of ham and a 1cup serving of oatmeal with a scoop of protein powder in it. She wanted to make sure I ate enough protein before going in... could the increase in protein compared to my normal diet be enough to have made it jump so high?

I also have endometriosis which causes internal inflammation, and my cycle started last night. Could this be more of a reason for the higher protein? Aside from the endometriosis and t2 diabetes that is controlled without insulin, I am relatively physically healthy.

I know plasma donation should NOT be viewed as a source of income, but unfortunately due to my disability I am in a position where I very desperately NEED the financial compensation.

I was told I can go back tomorrow, but it is difficult for me to cover the costs of getting to and from the donation clinic. I don't want to go back tomorrow if it is likely I'll be defered again, so if anyone who has experienced this or has endometriosis can give any advice or suggestions, I'd really appreciate it 💙

Thank you to anyone who reads this!

Edit- Update, went back today 24hrs later and it was down to 7.9, did the donation and it went well! All I did was go back to my typical diet and make sure I drank about 3.5L of water in the 24hrs leading up to going back!
