Anyone else have experience period “fake out?”

Some background context: I’ve always had rough periods. They were bad enough, my conservative parents agreed I needed birth control in high school. Sometimes, I’d even have flu like symptoms the first day or two. (Edit to add age: 27)

BC has been a fight. Insurance stopped covering what worked, so I bounced around different types with a variety of side effects until I just gave up.

Now, my periods are shorter and lighter than they were before BC, but I experience what I call the “fake out.” My period will stop for up to 24 hours, then come back with all the symptoms full force for up to 12 hours. And when I say full force, I mean murder scene in my underwear, debilitating back pain and cramps, puking, sweats, chills, shaking, headaches, the whole shebang. It feels like how it did before BC.

Is this a normal thing? Any advice on how to mitigate the symptoms?

I know endometriosis runs in my family, but I’ve yet to get a diagnosis (and anytime I bring up how much pain I’m in during my period or ovulation, I get told that’s normal and to take ibuprofen). But from what I’ve read, this isn’t an endo thing anyway (though I could be wrong).
