Menstrual Flu?

Wondering if anyone else has experienced something remotely similar.

Due to a back injury I’ve been taking a good deal of ibuprofen daily. My period is semi-irregular due to Norethindrone birth control, and now I am 3 days late (not a big deal since I know a lot of ibuprofen can delay your period a few days and I’m on the pill). HOWEVER today I have been dealing with the most intense cramps, coupled with a headache, body aches, sneezing, and a fever. I’ve read online that sometimes people have flu-like symptoms accompanying their period but it seems pretty rare so I hate to jump to that.

Anyone else experienced anything like this? TIA
